why would it be right for us as a society to kill those who we feel are a problem?
Exactly for that reason. They have not followed the rules of law or society and harmed people in society, why should they be shown any mercy?
I am thinking about the the estimated 1,477 million + (as of Saturday, July 25, 2026) people in India today. How do a 100,000 matter?
You have to kill them to show them that killing people is wrong.
Killing them would deter other people in committing such crimes. At least, Indians understand that language well. Leniency does not help. It exacerbates the problem.
