on a serious note, it really is. death/execution as a punishment makes no sense. there are fates worse than death for those whose offenses we'd love to spill the blood for. Alcatraz is one such place where those fates are served.

and for crimes that are not enough to execute for, bog-standard prisons are enough. they are imperfect, but those willing to change prove themselves there, and a good one should give enough opportunities for a criminal to re-educate, reconsider some of their life choices, and rehabilitate.

punishment by death is never the right fit.

We're not talking a finished crime where "peaceful" punishment is an option. It is an ongoing war, missiles destroy cities and lives. When someone is doing that to you, killing them is usually the only way to stop it. Surrendering is not an option, see Bucha.
