Fear the wrath of the spider

Fred was never a lucky guy. First he was abused by his parents and then bullied at school. And his bullies were even the cause of his death. He thought that he would have peace in death. The peace that he always wanted. But no. He and his murderers were summoned by the goddess of light and life. The bullies were chosen as heroes.. but he wasnt?! And to top it all off he wasnt even going to be reborn as a human?!
Forsaken by the gods and shunned by everyone, will he cling onto his humanity or will he let them taste his sweet vengeance?
