The difference being that judges are entirely happy to make precedent-setting rulings on what "use, copy, modify" et cetera mean. I don't think any judge would be willing to rule on whether a particular use of the software counts as "evil". Even if they're presented with a case where someone is using the software in an unambiguously evil way (like, I dunno, kidnapping small children to use as sex slaves) then they probably still won't rule on that, because that creates a precedent that a judge can rule on whether something is good or evil, creating difficult situations for future judges.
