That's because they are supposed to. Notice that the controllers in HL1 bare a striking resemblance to the Nihilanth. From the Half-Life Wiki's page on the Nihilanth:

"Half-Life 2: Raising the Bar states that the first part of the Nihilanth's name is reference to nihilism (from the Latin nihil, meaning nothing), while -anth is a common suffix that is related to flowers and is a reference to how his scalp peels open like a blossom." - Half-life.wikia.com

No matter what I bind fire to, I can't shoot or knife anything.
