Did you know after I dropped him off I got back in the car and drove away?
What is wrong with dropping him off?
I beat him to death with my shoe before I left.
There is no excuse for murdering people. Killing others is a serious crime that leads to life imprisonment.
The little fucker messed with the wrong person and he was asking for it.
Even if you feel messed with there are other options to punish the person. Do you have plans for what will happen when you get caught? It might be better to turn yourself in you could get a lesser punishment.
