The “he was a bad guy” argument is one of the weakest. There are objectively “badder” guys that are current or recent US allies.
The Biden administration refused to even sanction MbS after signing off on a report that he is responsible for Jamal Khashoggi’s murder. I suggest you have a look at the last hundred years or so of Central and South American history for a wealth of awful examples, but you can look at I think any continent except Antarctica.
In case this was interpreted as “what about-ism”, my point is rather that “he was a bad guy” is rarely a significant factor in foreign military intervention in the west. It is usually just a rationalization.
