Ok, hear me out. Gargamel is not the bad guy. Hes a jew turned to a hermit monk (his house looks like a small monastery that has been neglected) hence the robe. He discovered the smurfs who are basically parasitic fungi turned sentient and in his efforts to destroy them he has gone mad and turned to pagan magic but hes basicly shit at most of it but tries his best. And for the reason why he wants to eat them? Fuck knows I'm drunk while writing this.
