I love the philosophy behind veganism, but because of my choice of education I think I could never become one?

I am studying to become a Zoologist. I have dissected many animals (Pigs, frogs, worms, etc.) I've impaled thousands of beetles on pins that were killed for research, I've studied animals in captivity (working at a zoo on an internship) and I will continue to perform non-vegan activities for the rest of my life (probably). Is this unacceptable? If I live as a vegan in every way except professionally, could I still call myself vegan?
