Here is my verdict....
At different time points in the life of KS, JW could not....
1) be a sober and reasonable man
2) hold on to his love - Pia
3) have control on his temptations - Dubai episode with Pia
4) respect the tradition and meaning of marriage
5) love his wife completely
6) trust his wife completely
7) love and understand his second wife, Meera
8) keep control on his kids - If it was not for Pronita/Bani, each one of the GenX kids were headed to hell
9) maintain unity in the family (being the head of the family)
10) control his obsessive compulsive sister, Jigs
11) take care of his business - Meera, Ranvir, Jigs, Veer (to name the major players) had fun with it!!
Putting it all together, Jai Walia could not be an ideal - human being, lover, husband, brother, father, business man or uncle etc etc
I'll wait for your comments...thanks!
