As satisfying as that sounds, it’s a terrible idea. Make rape a capital crime and you may have fewer rapes, but you’ll have more murders. Why would a rapist allow his victim the chance to identify and testify against him? If the punishment for him is the same whether she lives or dies, you’ve given him more reason to kill her than to let her live.

The victim’s testimony alone shouldn’t be enough to trigger the death penalty. People sometimes lie, even about rape.
