the world is a simulation to improve your soul
Taken from Ethics and MMOs which is summarizing the Bhagavad Gita
games can teach philosophy through simulation, but game worlds are inherently limited simulations. Simulations are negative systems that distract from the real world.
What if you flipped that idea on its head and looked at the real world as a simulation (it's not unreasonable) created to improve your soul, and the struggles of the real world existed just as teaching.
If this is the case, then suicide prevents you from fully learning the lessons of your life, and instead the suffering is for nothing.
