A system with fewer assassinations is a better system, if all else is equal. Unfortunately, all else is not equal.

Democracy should be an alternative to violence: Instead of murdering the next Hitler, you can just vote him out. Unfortunately, this only applies as long as it works. American democracy has not worked for a very long time.

Not just vote him out, that solves all his future murders. Depending on when he was votes out, he still needs to be punished for all his past murders.
