You have two choices when facing aspas: you either run or fight back. KRU chose to run, they gave him too much respect and aspas noticed it and he proceded to destroy them. Sentinels, on the other hand, are standing their ground and showing no fear, even if they die doing so. KRU didn’t just lose the game, they lost to their own fear, to the aura they built around aspas. In the end, they were defeated by this unbeatable figure they created in their minds.
