The reason behind Incarnation Randy's dramatic change in behavior when compared to his prior inception's behavior was the result of his recovery from near death, and that was thanks to his main body healing him. Before, when he was created, as a result of his imperfections, he felt like a humanoid weapon devoid of most human emotions and behavior. Even breathing itself was unnecessary for the most part.
Even in his present state, he could still go by without breathing and he would still be okay. That was because if he so wishes the pores on his skin could viscerally carry out respiratory functions in place of his mouth and nose.
However, unbeknownst to Randy, when he used his Divine Points alongside the support of the [Synergy] skill to heal and resuscitate Incarnation Randy completely, he had also somehow managed to repair some of the damaged parts of his brain, which initially made it lack situational awareness, but it was only healed partly.
