There's merit to discussing whether his actions were beneficial or not. But for the love of god, if you've got a problem with him as a person, pocket it unless you know discussion of the specific problem you had with him will with certainty serve the public good. You've got every right to say what you want, but think it through.

I didn't know him, but I've known plenty of others with questionable reputations who've died as a result of mental duress. Before you comment, I'll ask as a bystander for you to think about whether everyone benefits from knowing what you wish to share. Otherwise, you'll just out yourself as an asshole.

Rest in peace, Adrian. Regardless of what you did, beneficial or otherwise, no one deserves the mind-shackles you had to live with.
