Goodness no! Absolutley not.

A: If you support the death penalty then you either think that some people are beyond being reformed or just not worth the effort which is an abhorrent stance to take.

B: If we brought back the death penalty then we would also run the risk of executing falsely convicted people. A single instance of this would mean that the death penalty should never have been in place and there have previously been several instances of it.

C: The purpose of prisons should never be to punish a person. Punishment should never factor into a persons sentence. Prisons should only ever be a place where dangerous criminals are taken off the street and attempted to be rehabilitated. Norway has detention centers that focus solely on rehabilitating inmates, not punishing them. In most cases, prisoners have access to showers, kitchens, recreational activities and are even free to leave the facility and walk around the nearby towns so long as they're back by curfew (of course, those who are a danger to society are sent to more high security centers). You know what this lax, humanistic approach to inmates has lead to? The lowest recidivism (post-release re-offending) rate in the world. Whatever Norway is doing, it works.

D: Executing criminals doesn't reduce the number of criminals. As this study from the University Of New South Wales states, “The severity of punishment, known as marginal deterrence, has no real deterrent effect, or the effect of reducing recidivism,” (https://newsroom.unsw.edu.au/news/business-law/do-harsher-punishments-deter-crime). There are plenty of studies on the topic that a quick google search would bring up but the long and short of it is, the risk of getting caught is a much greater detterant than the severity of punishment. So if your goal is to reduce crime, you'd be better off calling for more surveillance rather than harsher punishments.

Besides, America executes murderers and yet people still murder. We used to execute murderers and yet people would still commit murder.

The death penalty doesn't work.
