I think are misunderstanding his take on life.
He didn't kill himself because someone deleted his "wow character" but rather he lost everything that he had invested his life on.
Remember in today's world, gaming isn't for just fun, there is competitive gaming, and those guys can make more money that the average person, since they push all their time and effort into gaming.
This story take place in the future, in which the MC is the best competitive player, who just lost everything he had worked on, of course he would feel despair.
Imaging yourself spending decades in trying to become a doctor, only to one day permanently lose your license due to "an error" outside your control, and now you have nothing; it might not be the same thing to you, but to the MC is was exactly the same.
