I think ML believe that being in control (have power over someone or something) is the only way to keep everything going as he had planned.
Since his childhood, he seemed to learn that being perfect but powerless is meh. Then being powerful and got feared by others, apparently is a good control mechanism to have what he wanted, as planned.
There goes MC not going as he planned

I still don't understand the ml, I don't know his intention and why he wants to control the mc so much. I mean, I thought he'd be more empathetic or something but all he thinks about is how easy the mc was to control? I feel bad for the mc, to think it happened on his birthday too
