Why? Why do you push by yourself in late game when their entire team is missing? WHY?

Usually it's the ADCs that fed all day and gave up on life who do this. It annoys me to no end how defeatist some players are.

I've got a relevant story to this I was playing with two people in a skype call one time, One of them was going Nami, and was known for doing questionable things. The game is reaching its end with my team losing (but still holding on), and one teamfight could either prolong the game if we won, or end it if we lost, so despite the person on Nami occasionally doing stupid things, he still had use with his ult. During a short period that nothing happens, and everyone on their team is missing, he says this:

"I'm gonna steal their blue." First thought that goes through my mind is "Why the hell would you do that? You're gonna die." Knowing he wouldnt listen, I kept to myself.

HEY LOOK, THE ENEMY TEAM HAD THEIR BLUE BUFF WARDED Nami did not last long against the entire enemy team collapsing on him and complained about that being complete bullshit. we then proceeded to lose.
