When you are accused of rape, and you decide to try to murder the accuser and her family, should that be considered an admission of guilt?

Pretty much, yes. A defense attorney in a rape trial would certainly want that kept from the jury.

It’s a pretty good indicator.

Well not automatically in all cases, but it should be considered as a likely-related circumstance.

Of course, attempted murder is also its own serious crime…

Well. Hmm. What if he didn’t do it, but the woman accused him anyway, knowing it would end his career…..

It proves you’re guilty of attempted murderer not of rape.

But the question is, what was his motivation behind trying to kill her?

That’s certainly a very apt question, but it wouldn’t always have the same answer in all cases.

It’s a crime of it’s own of course and should be treated that way I think.

No. Like @gondwanalon said.

If he didn’t do it, and she accused him anyway, and it ended his career, then she would be guilty of slander.

More than slander, falsely reporting a crime is also a crime. @kritiper
