Don't put clauses that rely on subjective concepts (like "good" and "evil") in your software licenses, because they can render the license impossible to enforce.
What effect do purely normative statements have on licenses? Because the original only says you should use it for Good, not that you must use it for Good.
If you want your software to be usable, choose standard licenses and don’t modify them. Unless you find value entirely in creating something and not in being useful to others, be extremely careful with creative licensing.
