The lesser of two evils is still evil.

It's like finding out your two front tires are worn down past the safe point. Rather than taking the time to change them both out, you look at the worse of the two and say "Man, that's really got to go" and leaving the second one since it's not quite as bad. And then later on you can be shocked that it went flat and you wound up totaling the car in the ensuing crash. See: Bush/Roberts.
