Prison is not by definition dangerous. There are plenty of societies that find a dangerous prison to be unacceptable. And then there are others that seem to take grim pleasure in the idea that someone in Prison might be harmed.
The prisons that you're willing to put people in are dangerous.
You argued "innocents may die". Do you really want to amend that to "it's bad if innocents will necessarily die but okay if they die in practice so long as I can convince myself that they needn't die in theory"?
Prisons are indeed dangerous, but it is a matter of degree. You seem to be asserting that there is little practical difference between a life sentence and a death sentence in terms of opportunities to right an unjust conviction. Can you support that with evidence?
Should continue executing people who might be innocent until we can suitable reform the prison system?
One of the reasons prisons aredangerous places is the that socity is complicit with rapists and other sociopaths, giving them tacit approval to brutalize other prisoners.

Actually, I asserted that there is a difference, namely that if you're sentenced to death, lots of money will be spent after conviction on your case, both govt money and pro-bono. (The former is statutory.) If you're get a sentence of life without parole, there's no govt money and typically no private money either.
Do you really want to argue that point?
Folks on death row are not subject to violence from other inmates, so their only real risk is execution.
As to why prisons are violent, it doesn't actually matter. You're willing to use them, knowing that they're deadly.
