When Jin entered the Dungeon Maker, he already had plans in his mind on how he wanted to build his Monsters' Home. To create it in a similar style to an apartment complex or a high class condominium.
The similarities between a normal condominium and the one he was going to create ended there though.
Sure, he could do worse, like imprisoning them and using them when needed, making them deprived of hope and they could not do anything since the command of absolute loyalty would force them to obey Jin no matter what.
However, Jin did not wish to be that kind of person. He remembered the friend of Ming's who he took him out to fish once told him something. "Life is an echo. What you send out will eventually come back to you. So treat others how you want to be treated and that way respect will be earned."
