Lord krishna smiled and said " Hey praath tumhare raath pe niche me betha hu aur uppar shri pawan putar bethe hai , toh socho karan ne tumhara raath 01mile tak hila dia , agar hum na hote to socho tumhare raath ka wo kya haal karta"
Draupadi already call karna as sutputra in swayamvar still at the time of vastraharan he had feeling that if she ask help i will protect her, but she didnt ask help from him and just go away from him, he feels she still insulting him so he called her VESHYA(due to anger). For him she insult 2 times. so he insult once. And according to someone comment here, it was in DHARMSHASTRA that if any women having relation with more than one person, she get called VESHYA. If that is right, so what is mistake of KARNA? He said what she deserve.
Yudhishtir who loose his brothers and wife in game. Is it good of worst thing?
Eklavya:
what about EKLAVYA who is self learned archer, his guru took his finger as gurudakshina cause he feels he may be great archer than Arjuna. So absolutely there are archers far greater than Arjuna. So what about fairness and unfairness here.
Bhishma(blessed with swechcha mrityu, knows Brahmastra(other than karna in mahabharata, knows Prashwapastra which even parashuram didnt know which is knowledge of his previous incarnation as prabhas i.e one of VASU from asht vasu, his gurus are BRIHASPATI, SHUKRACHARYA, MARKANDEY, VASIST, and PARASHURAM) :
It is not possible to comment in short about this great personality, but still need to write something cause you are insulting my idol. In short i can say, if he wish he can do anything even KRISHNA(8th AVATAR) cant do anything in front of him, he was even defeated great warrior PARASHURAMA(6th AVATAR). And he was all time great worrier.
Now about war, he was intentionally kept Karna aside, cause from inside he dont want a defeat of pandavas. He known KARNA can easily great anger if he insult him. And everything works perfect for him, KARNA took oath that he will not enter in war field if there is BHISHMA.
When Duryodhan(actual name SUYODHAN), feels that BHISHMA was intentionally just stretching war time and not fighting to win. He goes to BHISHMA and start blaming him, at that time BHISHMA took oath that next day either he will die or war will be over. At that time kRISHNA and all pandawas got fear, cause it was obvious that no can defeat him, so it was definately pandava who will lose the war. So krishna send pandavas to ask bhishma how can they win tomorrow, and obviously BHISHMA's whole life was full of sacrifies and internally he want pandavas to be win so he said i dont fight infront of women(If he didn't reveal it, how can pandavas win? or kill(not deafeat) BHISHMA). So next day shikandi was entered in war and arjuna was hiding behind him/her. So that day BHiSHMA do not fight, that is only arjun who continuously throwing arrows by hiding behind her(is he really warriour?) .
And one more thing, krishna took oath that he will not use any arms in whole war, but when he feels BHISMA is uncontrollable warrior, krishna tried to use weapon but it was BHISHMA who knows that krishna is incarnation of supreme god, so smiled and just close his hand and respect him, cause he dont want krishna to break his oath(now you may understand meaning of oath).
KARNA(DAAN, SHUR, VEER):
hahhaah your making joke of him. If duryodhana will not accept him as friend, he was out of Mahabharata and lives whole life as sutputra and unknowing to the world which is much wasted than fighting as worrier.
You already knows about bird competition, karna was winner in that competition. Arjuna's guru is Drona(even not comparable with BHISHMA), but Karna's guru is SUN god and PARSHURAMA(6th AVATAR), So can you comapre them?
Before start of war indra(father of arjuna) comes in form of brahmin and ask karna for his kavach kundal, where as SUN god(father of karna already warned him about this thing). So even knowing the brahmin is Indra he gives his kavach kundal(if they are with him, how can arjun defeat him if no arm can penetrate it). When indra get to know he gives his kavach kundal even he knows i am indra, he happy with his DANI nature, and gives his VAJRA(armer) and said he can use it for one time and then it will return back to him. And krishna use trick in same night and make him use it against gatakauch. If he use that armer in war ARJUNA was no more exist.
During war it was krishna who sent Karna's mother to told him that pandavas are his younger brthers and he was elder in all (BHISHMA knows Karna is elder of all). It was trick to make him either in pandava side or dilute his mind so he cant participate full fledged in war. Pandavas do not know at any time Karna is their elder brother, cause they must be fight against him in full fledged.
About Abhimanyu. Arjuna was first who kill Karnas son, so he was just took revenge of it.
In war when karna was on full fledged and almost on defeat of Arjuna it was KRISHNA who hide sun, actually here karna can still use his weapon to kill arjuna but he respect rules of war(where as arjuna didnt follow it while killing Karna). If Arjuna is really powerful than karna then why should KRISHNA suggest him to kill KARNA by breaking rules of war(may be krishna knows internally karna is more powerful than arjuna, so dont want to lose chance to kill him.)
In war when bhishma's or karna's arrow hit arjuna's chariot it was moved backword to 1 step, but when arjuna's arrow hit chariot of them it moves 4-5 steps, so he arrogantly laugh on his power, at that time on the end of war krishna says him, it was me who hold waight of earth on your chariot, and it was LORD hanuman who kept alive this chariot still now, in actual your chariot is already destroyed long ago. Bhishma's and karna's arrows hit more powerful than you.
One more thing to say, when arjuna killed(do not defeat) karna, he laughed and use some bad words against karna, then Krishna scold him and showed him what is Karna. Karna was on die, one person on war ground begging for his son's anthyasanskara, after hearing his voice he called him, try to give his golden teeth but unable to remove it so using stone, he broke his golden teeth and give it to that person, So even at the time of death he do DAAN.(Who can do it?)
I am not against krishna or arjuna, Definately Krishna(8th AVATAR) is god so we have to respect him, but these 3 guys are uncomparable and perfect idols for today, a self made persons. Tricks and tactics are more used by pandava side. And in WAR they didnt defeat any one of this great warriors, instead use wrong methods to kill them.
