I just don't get why you'd be on board with death penalty at all.

What does it solves exactly?

It's so abusable and there's no take back... I feel it's mostly an emotional solution to material issues... It also has been proven to not have a detering effect.

It's mostly the same as torture. Ineffective, abusable, permanent.

I'm not saying this as an attack or something, I'm just genuinely puzzled at any kind of support to death penalty.
