I personally have had to deal with someone who, IMO, is a psychopath - he forced the rest of us out of this non-profit using manipulation, etc while the rest of the organization (i.e. everyone else) make the mistake of empathising with him (assuming his behaviour was the result of personal stress). At the end, he flat out stated his end goal was to derive a salary from the donations the general public was making to the org, contrary to the organization's constitution... He's now commercializing the heck out of things while having a personal (and unstated) financial interest in the commercialization.
I stupidly hadn't asked enough questions about the back story of how this guy got involved with the previous incarnation of the organization - he came in, stirred up trouble, drove out the existing leadership and due to their missteps, was able to portray his behaviour as reasonable... when it became apparent he was losing some level of control over the current org, he did it all over again. My fault entirely for being not cynical enough and the other people for believing in his bullshit.
I understand your point of view, but until you have been in a real world situation where the legal system is COMPLETELY USELESS, you will never really understand how the world really works (aka reach 40, not a conservative, no brain etc). The amount of ambiguity inherent in evaluating human behaviour is a lot more than you think, and people like this use it to their advantage. And the legal system is very expensive, so trying to use it to achieve 'justice' tends to be, overall, not cost effective. The legal system is ONLY about monetary issues.
And people like Appelbaum know this - they know how to skate the line and to use the weaknesses of society, social relationships, the legal system ... to their advantage. Reading about Appelbaum triggered all my triggers about people who should be avoided. I really "get" this ideal of Solomon-like impartiality, but facts / evidence / scientific-ish attitude... you have to also understand people as well besides this to grok the truth and that requires actual wisdom. And over 40, you begin to understand that an awful lot of people have zero integrity, especially those whose primary goal is power of some sort.
