Obviously, the message is to point players towards good, but that isn't really the game's business.
In some cases, it could be the DMs business, or at least the groups business.
But I would prefer things like poison or anti-paladin's to be in the DMG not because they are eviiilll but because they are less core and more campaign optional then say, halflings (though I could totally see some groups not playing with halflings). On the other hand animate dead or cause wounds should be in the PHB, along with all the other 'evil' material, e.g. that which allows you to harm, trick, or control others, which is about 85% of the page count.
