Connecticut abolishes the Death penalty

So behaviour is justified by being part of human nature? By that logic, murder is justified and ipso facto capital punishment is not.

There's an oxymoron for you.

You contradict yourself.There is no evidence that a crime occured. The defendent is, by definition, innocent of a crime which did not occur.

Justice depends to a great extent on risk. Where there is a significant chance of being wrong, it is decidedly unjust to invoke an irreversible penalty.

From my perspective, justice is a fitting approach to a crime. It may involve rehabilitation. it may involve restitution, where possible. It may involve removing the criminal from society in one way or another.Justice is, simply put, doing what's "right" - for the victims, for society as a whole and yes, for the offender too. To suggest that you can do what's right without regard to the possibility/probability of making mistakes is, frankly, ludicrous.
