Murders done by SRK in Baazigar.

I too agree. Bad planner. 

That movie got under my last nerve. Both SRK and Kajol's characters

He killed Shilpa because his sister died because of Madan Chopra. He wanted to give him the same pain his parents got. It was a planned move. He always knew he would kill her. The other two murder he did was to cover his crimes.

But he lost his father and sister too...so madan and one of his daughter had to die

Firstly, it's okay to say he was a bad planner because again Shah's role here is a psychopath. He is in lines of Joe Goldberg. 

However, he had clear motives. He killed Shilpa because he wanted Madan to suffer and she was his daughter. Now he wanted to get close to him so he targeted Kajol. The other two murders was to cover his crime. 

If you watch now in 2020 which came on TV recently 

This Raj malhotra or sharma who ever SRK was - his plans were all hay wire and confusing 

By luck kajol and shilpa did not catch him off gaurd

Kajol caught him in end after so many clues

Shilpa never could guess his motives at all

But the three murders he did was wrong actually 

He could just act rich get into good books of madan chopra thru marrying one daughter and than snatched the empire instead of such stupid plot

It's not about his motives , it's about his plans which were silly and badly organized

I don't remember much about the movie.

Why are you badnaaming SRK? Murders by his character in bazigar bolo na 😆

Bad planning ke baad bhi itna time survive karne wale ko Baazigar kehte hai.
