I think in the short term we're kinda fucked. But in the long term I would like if we tried to make these crimes not happen. Find out why they're happening.

Can we help these criminals before they become criminals essentially?

And I wasn't saying we should get rid of prison, rather allow the person to choose death if they wish.

I'd also like to see if we can actually slowly introduce them back to society, slowly give more freedoms back or help them take jobs that gives their life meaning.

It's a hard problem and we definitely don't have the correct solution right now.
