First, let's stop using the term 'alpha' to describe a dumb jerk.
I think I was making a fine distinction but you're right, it implies an excuse where there is none.
A person of poor character may yet have strong attributes; business acumen, athletic prowess, professional and financial success. These attributes *do not* excuse bad behaviour, but they're nonetheless innate competence and ability which cannot be easily discounted, although they're easily overshadowed by a lack of character.
A person of poor character who has done little more than purchase and memorize serialized pulp fiction, is even worse IMO. Those aren't achievements, they're habits.
But they're both terrible examples of human beings regardless -- you are correct. They're just different flavours of bad ... different varietals if you will.
It's an interesting problem: some people are bad because they have power, others because they seemingly have none. But both of them are trying to exercise it over others.
Then there's a lot of nuance regarding what is and isn't earned, etc.
These are ancient human problems that are unlikely to go away.
