[Mitsunari fails to react to the arm around his shoulders, only frowning at Motochika's words.]

It devalues true suffering to treat all grief as equal...! I have no reason to ease others' minute, insignificant pain, especially not when it does not concern me.

[Well, obviously, some things he's not willing to budge on just yet, though at least he isn't going to belittle Motochika's pain any longer. It's the "when it concerns him" part about that statement that's key here. His lords aside, whose welfare he was naturally invested in, there was always Yoshitsugu. In the end, he never knew the true dark side of Yoshitsugu's personality until after his death, but what Mitsunari did know is that he suffered. He had neither sympathy nor mercy for anyone who would dare make life worse for him.

Within him, he clearly has the capacity to want to help others. It's just people who have no relevance to Mitsunari literally may as well not exist.

He does shrug off Motochika when he sort of gets his wits about him again -- the gravity of this conversation has had an effect on him. However, there's no anger behind it.]

Get off.

[Your arm is heavy, Motochika. Have some consideration for others, geez.]
