Right. For sure, countries with death penalty have lower capital crime rates. Right?!

Feeling and believing in spite of the facts is called fundamentalism in other contexts. You might as well argue by the bible's "eye for an eye".

To make one thing completely clear: I do not condemn you. And I am not on a misson against the death penalty. But I would hope you might reconsider in how far your "feelings" and "firm beliefs" are telling you the right thing.
