Well, the thing that people generally like about humour that is based on someone else's apparent stupidity (or clumsiness) is...it makes them feel smarter than someone else.

That's what a bunch of people here on this forum also like about endlessly fighting with other people about various stuff, insulting them and calling them names. It's self-ego-enhancement.

If your compassion and respect for others tells you this is wrong...as appears to be true in your case, leeneia...that speaks well for you.

Another basis for a lot of humour is the catharsis of humanity's common fear-related issues...that is, seeing a humorous situation where a character (such as Charlie Chaplain, for example...or Woody Allen for another) is in a frightfully awkward, scary, or embarrassing situation.......that provides humorous relief for the audience. They wouldn't want to be there themselves, but they get a sense of great relief from harmlessly seeing it happen in a drama, and the discharge of tension is marked by laughter.

This seems healthy to me. It's been a basis of humour for as long as anyone can remember.
