Oh come on, KSP is about a space program with no defined safety standards (besides maybe player-defined standards), without death these safety standards can't be created by the player effectively creating a space program that fires a rocket that can't even get past 30km before running out of fuel or exploding on the launchpad. Death is a central part of the core gameplay and without it, players can't create a safer, more productive program.

that is true
