TIL that 35% of men report at least some degree of likelihood of raping if they could be assured they wouldn't be caught or punished.

Pretty sure its like 99% under the right circumstances.

War is a little different, you don't know if your gonna live to see tomorrow, the woman are part of the people trying to kill you, and rape is a tool of dominance, your scared you may die and raping the enemy is a way to cope and say that your in control. I'm not saying I condone it but it's way different then, "Yo that bitch is smoking, I'd rape her ass if I wouldn't get caught".
