[Objective]

I'd jump in front of a train. Those shits go fast as hell and will leave you in a cloud of meat. No pain, no nothing, it just rips you apart so fast not even your clothes can hold you together. It's egocentric as fuck cuz you'll traumatize some people, but ye, that's the most surefire way of going without feeling any pain unless you miscalculate your jump and hit the side of the train instead, lol.
