I have come to a conclusion that my dean of students looks like the danimals monkey
Are you relating the dean to the negative appearance of a monkey?
I don't think that both are related, but the danimals is cute.
There is nothing wrong with comparing someone to something cute, but it's not correct to insult someone when you feel the opposite. If you find them attractive, you have the right to feel that way.
I don't need to think someone is attractive in order for me to be nice.
I would say the same thing. Physical beauty should not be used as a base of how nice a person is nor should it be used to disparage someone.
