No did not mean for him to commit suicide.. but look for a way to escape or get a message out to someone through the daughter or that.. He hasn't once tried to get a message out to someone somehow or even thought of plans to escape. Not once has he tried to ask any of the girls especially the daughter if there was a way to get a message out. He could of even done the message in a bottle or that and threw it out the window hoping someone would find it and send the message out. It is that he has not tried to do anything.No, why would this be the case for one of the world's most powerful artifacts?
The only drawback seems to be what was explicitly stated. that it can only mind control 1 person at a time. Which the king explains why he doesn't use it on someone else. were he to do so, MC will be freed until he can switch control back to the MC. giving the MC a window of opportunity to escape.
He is trying to control the way he acts. As he feels it is about to turn him into a puppet trapped in his own body. By fulfilling the exact command before the puppetting stage, it allows the MC leeway in the exact methods of execution of the orders.
Specifically, it allows him to be gentle towards the girls and not violently rape them.
He is not in an apartment building, he is in a castle. with guards. and windows that are too small to fit through.
Also, again, literally mind control. He does not have the option to escape or commit suicide.
IIRC he was explicitly ordered not to.
This is also why the king holding him hostage explicitly notes that if he were to use the eye on someone else, the MC might escape in the time he is not mind controlled.
Also, it is pretty stupid to commit suicide after 6 weeks of captivity when you know you are backed by enormously powerful people (2 queens, one king, and a powerful nation) who will rescue you soon. The MC has children and wives to consider the well being of.
Aside from that, he is a magical beacon revealing his exact location at all times. the longer he is alive, the more exposed his captors are to retaliations.
Spite would dictate you stay alive and reveal the location of the enemy headquarters
And then you will kill everyone with your sick katana skills. since handedly slaughtering entire armies.
while farting lightning.

The part about killing one self if was a slave.. he is not a slave a prisoner but he is not a true slave being forced to do hard labor.. but even as a prisoner I would be trying to find someway to escape. The thing is not just sitting there being passive.. message out the window. The second thing is to be resistive and not passive.. being passive gives them more control over you easily.. you resist completely even if it appears hopeless.
