Maybe he's as bad as The West insists he is. Maybe all the evidence of his war crimes and crimes against humanity are real and not fabricated.
It doesn't matter.
We Westerners (and we people discussing it in English) are the last people entitled to an opinion after what we did to Libya and Iraq. Maybe a lot of people here were just kids when Libya was destroyed, and a lot of people here weren't alive when Iraq was destroyed, but when you say "this Assad guy seems a little off" that's what leftists were saying about Qaddafi with his weird plastic surgery lips and chin and his 'Bodyguard Harem'.
We don't get to sit here and weigh up the mountains of evidence against Assad and discuss amongst ourselves what's real and fake and come up with a net positive or negative opinion. Every time those kinds of discussions has happened in English, it's just ended up enabling and approving atrocities.
We need to recognize that we don't have enough reliable information about him - especially those of us in The West - and we need to recognize that feeling the need to have an opinion is a symptom of our interventionist culture.
