You have to consider that the lawsuit was likely extremely stressful and scary.

I'm sure it was. Let's also keep in mind that he was offered a 6 month plea bargain.

Yes, it sucks to accept a plea on something that you think was not illegal. But if we are going to argue that he killed himself because of the charges, we need to admit that he killed himself so he wouldn't have to spend 6 months in a minimum security prison. Heck, it might have even been house arrest.
