> He wanted to work on his research and get grants not teach.

Working on research that's worthy of grants is extremely taxing, and is the part that makes universities function. Teaching undergrads is a chore.

I understand but the students are the ones struggling due to an absent teacher. I’m greatful he wants to do research but jaded due to the fact he doesnt care about the class or students.

My education was subpar due to his lack of effort.

Oh don't get me wrong, I'm only too aware that expertise in a field doesn't make you a good teacher. I did badly in some subjects for the same reason, I feel.
