I wouldn't say they are evil. In fact, both signed and unsigned are the same--the only difference is the "pain point" (the place where you subtract 1 and your world breaks) is in a different spot. 0 for unsigned, INT_MIN for signed. Both are perfectly fine as long as you stay in their good range.

Yes - but 0 is much closer to the range most people put in their integer values than INT_MIN. The cliff you fall of off is far closer with unsigned integers.
