Okay, since I can now, I'll address this a bit at a time:
Firstly, I think we agree on the concept of a heinous standard. Where we are disagreeing is what makes it and what doesn't. So, for example, I may think Villain X makes the heinous standard based on their sum total of evil deeds, whereas you may/probably will disagree. I think that's the big issue here; one person's monster is another person's "just another bad guy".
As far as "using their resources to commit crimes that are commonplace", I simply don't agree. Because, for example, murder is common as a crime. Tarkin used his resources to commit lots of murders. Does that invalidate him? Of course not. What matters is the sum total of evil deeds committed by a villain and whether or not it's enough.
So again, we agree that there is a heinous standard, it's just that I think your criteria for it is a lot stricter than mine. To me, only the following is standard-fare villainy:
Trying to kill the heroes
Trying to take over the world
Being a jerk
Anything else is what I call "non-standard villainy". But obviously, things like just one murder of an innocent or just one rape, are not enough. BUT, several evil deeds all totaled for a villain who is noticably bad for someone at their level of resources, should be evil enough to fit.
That's my stance, anyway.
