The speculation is totally stupid. Why? Because there is absolutely 0 evidence that finasteride turns people into mass murdering psychopaths. There is no link. You need to find a “special someone” who will behave in this way. You cant rationally explain this behaviour. Its beyond comprehension. Even if he were completley impotent, had a shrunken cock and had brainfog, it wouldnt be enough of an explanation for this behaviour, as otherwise half of this forum should be committing attrocities. As I said, you need a special kind of psychopath, for this to occur.
And we really shouldnt compare a person who committed suicide (Dr. Stewart), with a mass murdering psychopath. It doesnt make much sense.
