In Harry Potter and the Methods of Rationality, Harry is confused as to why Lucius would want to harm an innocent girl (Hermione). He's told that Lucius knows that Dumbledore will expend resources to protect Hermione. Since they are enemies in frequent direct conflict, every bit of effort Dumbledore is forced to expend on anything else is that much less effort he can expend on opposing Lucius. Any time Lucius can impose costs on Dumbledore without any negative externalities for himself, he should do so.
