its not opinion though, go look at the evidence.
your thinking is backwards, you know believing something despite the evidence.
how is capital punishment not reform. you guys really are delusional, saying anything you can to defend and untenable position.
the evidence out their in clear sight, go look it up. there's an absolute mountain on human behaviour as well as rehabilitation, how to reduce crime in the first place. look at countries with sensible drug policy, sensible prostitution policy etc.
in a fair and rehabilitation focused system, you cant have death penalty, you will kill innocent people etc, so your argument still doesn't hold any weight.
