Omkara is multidimentional... why are we trying to classify him..
He is different with his brothers.. he is fun loving and jovial yet there is a flawed side to him.. He is unable to cope with the demons hes plagued with.. for the most part he can handle himself but when it goes out of control he isnt able to...He is flawed when it comes to his parents.. He probably has seen alot of bitterness.. fighting.. hes seen his father openly keeping a mistress.. his mother turn into an alcoholic. I think trying to judge people based on their achievements and independence is incorrect.Shockingly some very so called happy seeming people and sucessful people are the ones that suffer depression, drugs and suicidal tendencies.. see Robin Williams, Heath Ledger, Jiah Khan. Even Deepika Padukone recently spoke about her depression..So just cause Om seems so happy and self confident doesnt mean he doesnt have his own demons to tackle
family as big as oberoi's are sure to have loose character men. may b O has more of jhanvi in him which propells him to succumb to alcohol. and he is the eldest of the clan as well. lets see whether he remains weak or rises at par.
anyway i loved your POV as well..
but the best was when he recovered he started worrying for shivay.. love him
