Like other members of the Ōtsutsuki clan, he was completely indifferent to the lives of others. In his eyes, only his own survival and his relentless pursuit of eternal life mattered most. As for how many innocent people might perish along the way, that was entirely outside his consideration, because ants deserved no attention.
For instance, his treatment of companions was ample proof of his cruel nature. Even those of his own bloodline were merely tools in his hands to be used at will. In the original course of events, he had unhesitatingly plotted to sacrifice his fellow clansman—Momoshiki's "vessel," Boruto—solely to ensure the successful cultivation of the divine tree.
Such behavior not only demonstrated his utter disregard for other lives, but also exposed his ruthless determination to achieve his ends by any means necessary. No matter the situation, Jigen never showed mercy, because in his heart, nothing could compare to the realization of his personal ambitions.
