I understand this, but there's also the dimension where his actions, whether true or not, are also damaging other people (Gavin's reputation is on the line).

We'd all be more worried for him if he wasn't so blatantly causing harm to other people's reputation.

Obviously he could suffer from severe mental illness, which combines elements of harming others and self harm, but as a society I think we should worry more about the person being harmed (ex. Gavin).
