@Kukuruku after the goblin trauma of his childhood, he was trained by a weirdo rhea that tormented him while training him up to kill goblins. A twisted, inverted personality is pretty much a given. Fortunately he starts hanging around people again eventually and actually develops his personality beyond goblins. Something his friends were quite right to be concerned about as that path led on a one way trip into the darkness. This world ain't sunshine and rainbows, here there be monsters...literally.
