the barrats is an ideology or group. We believe nobody asked to be born or raised, but wish to not cause harm to those around us.
Our belief is that once we graduate, we can take measures to comfort people the most we can before we commit suicide. This includes getting your parents a pet or friend, buying life insurance so that those around you can receive financial aid from your loss, etc. but to make sure those we care about won't suffer when we die.
Upon distancing ourselves from loved ones, we will try to kill ourselves peacefully.
There is no oath or weird cult stuff involved. Just be a good person and wait silently until we kill ourselves.
I've already decided once I turn 20 I'm killing myself. there are things I will do to try to make my death simple and create as little of an impact as possible.
