Absolute morals?

For example, if a stranger rapes or molests someone you love, is there any circumstance under which it would not be wrong?

I don't think we would be able to, no...  we can't question or challenge 1 + 1 = 2, not credibly at least (1 + 1 = XD!!  GTFO). So, since we can challenge any morality that pops up, I don't think there's absolute morality.
