Choice of Reward
While their individual goals seemed to be quite similar, the differences between Jason and the Soul Monarch were crystal clear.
The Soul Monarch had no morals, and didn't even hold back from killing innocent people, such as children, the old, and even the disabled.
In fact, the Soul Monarch loved to exploit them as they were the best leverage he could have against the otherwise stronger beings such as the powerhouses in order to attain his goals.
Jason was the complete opposite.
He would never intentionally kill children, the old or disabled people as long as they were innocent.
There was a difference between being doing something purposefully with the intention to hurt others and innocent.
However, once it was necessary and there was no other way, even Jason wouldn't hold back from killing others.
After all, his own life and the lives of the people he held dear were far more important to him than the lives of others!
