Would you be able to forgive yourself or pretend you never did it, if you killed someone??

I would if the person did something bad to my family or if it was someone that I needed to save the world from like pedophiles, rapist, child molesters and serial killers. No I wouldn't feel bad not at all but not an innocent person.

Absolutely.

there are plenty of people In my life that not only deserve to be killed,

but they actually should be killed.

never
