Highly agree with this, people don't realise that despite the MC being all powerful. If there are shady people, he doesn't know Jin Ho's father well enough to give the benefit of the doubt, his family would be in danger, as seen how despite him attaching shadow soldiers to his family, there are still people/monsters out there who can outpower those soldiers. And before anyone will say he has those top shadow soldiers, he would only leave them when he is not fighting, if not you will realise he always keeps his strongest by his side.
