No. It goes to my understanding of time travel and how it has been discussed and treated in science fiction. it’s the best we have, since there is no one that has actually gone back in time.
The issue is that you never affect JUST ONE thing. Actions have consequences – even the smallest thing, like stepping on a fly, may have serious consequences a generation or two later. Stopping a rape, which is a much bigger thing, might have HUGE consequences – family feuds, riches versus poverty, who knows?
Changing ONE fact essentially changes history for everyone – possibly the entire world. So while a rape may be odious, I think it would be immoral to change the entire way of civilization (yes, it could be that important) because of that one activity.
