I think he loved Skeletor.
Only if you want him to be, as far as the original Funimation version of He-Man goes
it's a children's cartoon, and there are a lot of subtexts that you can read into it as an adult.
The Disney remake of He-Man goes into a lot more explanation.
Such as where did Skeletor come from and what happened to make him look that way.
Exactly what is Skeletor's problem and why he doesn't get along with He-Man.
How He-Man came to have that magic sword and why he has divided allegiance
between his father the King and the Sorceress.
Why there is upheaval and unrest in the kingdom and how it got to be that way.
The Disney version of He-Man seems to be aimed at an older audience
like teenagers or young adults instead of the 8 to 12 year old set the original pitched to.
