How often do you hear about projectiles completely going through their intended recipient and having enough energy to do harm to a secondary target, versus the shooter missing the intended target and striking something that they did not intend to?
It is exceedingly rare that "shoot-throughs" happen where a secondary target is injured.
People getting hit who were not supposed to is an entirely different matter, but that is a marksmanship problem and not a projectile performance problem.
