If you're comfortable with/want the Joker tagging your character's entries with no fear of what he might say or do, please reply here so I know.

For the record, I will not ever have the Joker "on screen" murder a child or talk about murdering a child (he might threaten it, but he won't do it where you can see or talk about having done it). The only exception is he might tell your character he killed a kid and then pull a "just kidding".

Also, the Joker doesn't bother with rape (except, ummm, that one time with Harley) so no characters will have to deal with him talking about or making allusions to that.
