Is kylian mbappe the most selfish player of this generation?

mbappe is injured He has been playing with pain for 6 weeks, but it became unbearable during training today.

Concern is it getting much worse and him missing later stage of the season and World Cup if he keeps playing..if you have been watching real Madrid games for the last 6 weeks mbappe has been their worst player why was he playing when he could've rested and gave other players a chance ??
