Richard didn't know what he was getting himself involved in. This was sick. He was two floors promoted just within a single week, and now, he was going out there, in an arena to fight someone who was possibly stronger than him.
Just a week ago, when he entered the Endless Hold, he didn't have much expectations against the prisoners on the higher floor because of their lack of strength. He was too reliant on his batons and potions. But, now, he has no options.
However, this was necessary. He has to discern the strength level of the prisoners here, and accordingly plan his next step, how he would be slaughtering them. No one was innocent here, so Richard didn't feel remorse at that thought.
However, just because of the same fact that no one was innocent here, it loudly stated that if he lost this battle, then Richard would die.
