What is evil? Is it something you are, or something you do? Are there evil fonts? Some say that Comic sans is evil - but there's a perfectly legit reason for comic sans existence.
Still, now that Comic Sans has escaped its designated area of children's games, and run out into the real world its being used in all the wrong places. Take this example that "merges" (Adam Baker) photographed somewhere in Canada, it's such a gem of an example that translates to "comic sans must die" in any typophiles eyes. This may not happen again - god I hope it won't - sure, nobody was killed this time, but you don't want to risk it again. Right?
