Well at this time Sam already came from that place and he was now resting to recover his spiritual energy. Even though he got injured by those Monsters, he did not get that much injured and he already recovered his full health so he did not have to worry about that. But naturally as you can tell he was just thinking how long it will take him to complete the mission. Because he wasn't alone fighting those Monsters and also because of those other Warriors he also took much time to kill those Monsters and was unable to use destructive moves.
Well, if he was alone in that place then he would naturally use the mega fireball and also at the same time the newly learned move called The hell zone. But the thing was that all of those moves were very destructive and because of this those other Warriors will also get affected by that and they could also get injured.
