If you gave someone a dollar to buy you a beer and they killed someone on the way home, would you feel badly?

If you had a party and let a guest drive home drunk and they got killed or arrested? Would you feel bad?

Better yet,

If you lost a child to a predator, that they met in a casino/bar, then bankrolled a sting to bring him to justice, which allowed them to go on to kill a woman in a casino in another country?

Would that absolve you of any guilt or blame?

I do not think I would have any problem feeling like poop for my involvement.
