#1 Use for a Time Machine

Yeah... there's that too.

A hypothetical time traveler could have to reckon with the rippling cascading effects of his actions. Killing someone BEFORE he or she became evil, makes them innocent victims and AS SUCH, and not as evildoers, they could be remembered afterwards.

This without minding the fact that the situation in the late 30ies WOULD have fallen in war even with no Hitler about.

Funky time traveling mechanics... until it'll happen for real we can only speculate.

I once saw a Twilight Zone type show with this plot:

Man travels back in time and kills baby Hitler as he is on a baby carriage/pram walk with his nanny.

Fearful nanny then sees a distraught mother about to kill herself and her baby (wow, what a coincidence!).

She rescues the baby and takes him home.
