Jokes aside - I wouldn't name them the same name as a psycho killer or whatever... but I would name them after a rockstar who overdosed
LOL!

I think if it's a less obvious connection and it's not "modelled" off a murderer or mass rapist then go for it.

Then again, imagine how many murderers there are out there? can you really guarantee you won't get a murderer's name for your child?

Sorry, 4 hours sleep so logic out the window. but hope i helped. Now to pump more caffiene into me!
