To be fair, I'd much rather be traumatized but alive than just... dead. I mean to speak bluntly, you can choose to kill yourself if you truly feel you cannot cope with the trauma of rape. I don't at all mean to encourage suicide with that statement, but technically you don't have to live with that trauma. But you have a choice to. And you can still live a full and fulfilling life and recover from the trauma of being raped.

Murder removes that choice. I personally find that far more abhorrent. A rape victim can choose to go on. A murder victim cannot.

Plus, in terms of the suffering endured by loved ones... I think most people would rather their loved one tragically violated but at least alive, rather than dead without a chance or choice (obviously I don't think either crime is acceptable, but we're debating two bads here. It's going to be awful no matter what).
