Eric was happy the Judeo-Christian apocalypse happened.
He wouldn't say it was impeccable timing, but for starters, Hell had the right idea. For a thousand years, Eric had been roaming the earth, watching decade after decade pass him by and the status of his home planet sink deeper and deeper into an irreparable destruction. With pollution and extinction and the ruining of the circle of life and the overpopulation, Eric hated his existence. Humans just didn't taste like they did when it was the earlier centuries. They all tasted of oil and gasoline nowadays. It was disgusting.
So, when Eric heard the plans through the grapevine of one higher level demon trying to open the gates of Hell, Eric doesn't stop it. Hell, he pretends nothing is even wrong.
Humans needed to pay for the damage they caused to his beautiful, green earth. Vampires were created in God's image, not humans, and through this apocalypse their Lord would teach them of the wrongs they had committed, the sins that had been too great to heal. Eric was only religious for his Gods, the old, ancient Nordic wonders that haunted his dreams to this very day, but he believed implicitly that human beings deserved to be smote by the very hand of the God they so reverently believed in. They needed to be taught the lesson that you cannot destroy the planet you live on. You cannot shit where you eat. You can't reap what you sow.
Foul, dirty, disgusting creatures. Greedy. Selfish. Blood thristy. They were more blood thirsty than vampires.
Eric was happy the Judeo-Christian apocalypse was happening.
They fucking deserved it.
