Goku and Dr. Gero in “Unfinished Business”

There's way too many innocent people around here. We've got to lead these two out of the city.

Yes.

Huh?

It is too crowded here. I agree. Many people could get in our way. I will see to it that they do not. [Dr. Gero uses his eye lasers to blast the entire city, killing all the inhabitants]
