Kind of a misunderstanding. Its not “law” they lay down, its archetypes. If it is realistic it means more like it is more relatable.
Immortality and immense power is meant to give a sandbox view of the world with lowered consequences. Also the naive inheritor in case of Invincible.
In case of The Boys, Homelander embodies the establishment that is not only more powerful, but hailed as the hero of all mankind.
Thats lots of peoples vibes. You are not the hero in shining armor. You are an insurgent at best. You dont just get on a suit and start saving lives, but you have to go up aganist THE establishment and fucking prove yourself first. The very thing that is being actively hailed.
