I loathe him.
I like the sound of that one.
Loathe. It stretches out the tongue and draws the lips together.
Loathe. Webster's says that it expresses utter disgust and intolerance.

Execrate. I execrate him and all he stands for.
"to declare to be evil or detestable"
Sounds ******, just like him.

I abhor him.
Abhor--to regard with extreme repugnance.
Abhor has that hard air sound in its middle like the sound made when
preparing to spit.
Yes. That works.
Except he's not worth spit.
