I just want to join yours. Have you considered some nonlethal practice runs. Like giving people a bad case of the trots?
Ultimately there's no real point if you're only going to get to do it once. The whole point of being an assassin is multiple assassinations, systemically rather than a spree.
I'm just saying. You have to think ahead, you know? Plan for the future.
Your options are going to be much more limited from prison.
