Okay, this may seem like a really dumb question, but please think about it. Do you think Karan killed Surya? And what do you base this on? I'll give you my response to get the ball rolling:
No. While Karan is responsible for betraying Suryakant, causing him extreme pain, and laying the groundwork that led to his death, he did not KILL Suryakant. Laxmi's father was walking down the street, perhaps not paying attention, given the trauma he had just been through. But the couple driving the car KILLED Suryakant -- not Karan. There is a distinction there.
I may be simplifying it but: let's say a husband/wife had a really bad fight. The wife is devastated her husband is leaving her--a total surprise to her. She goes out for a walk at night on side of road. A car accidently clips her, resulting in her death. Did the husband kill the wife???
As always, I'd love to read your replies!😊
