Yeah, you can become a saint by going all kind of weird shit... Come on, anyone can kill a half salmon half snake, it's nothing that special. One specie gone extinct.
In Finland we have this Saint Henrik. A priest on a crusade to Finland around late 1200's. Henrik and his companions stopped by a farmhouse, took all the food and beer, and left without paying. The "man of tha house" wasn't home then, but when he got back and heard what had happened. He took his axe. Went after Henrik and killed him. That's how Henrik became a saint. For for being a priest who robbed a house and got murdered because of it.
