Orthodox Jews believe death penalty should be allowed for certain crimes today (allowed in Torah).
Many Rabbis and Jewish scholars said the guidance in the Torah makes it nearly impossible to issue a death sentence (shows, where the death penalty is permitte, should only be with greatest caution).
Israel allows death penalty for acts of genocide, treason and murder, but it’s rare and there’s wide debate about abolishing it.
The death penalty exist s as a deterrent, not retribution.
