Hmm...

Like someone said early on in this thread, Tanya's statement

He (Ink) wants to end it.

Yea, so the group thinks Ink did not start it, but who doesn't want to end it?

I do not quite understand his actions and maybe I am not supposed to, because he is psycho.

He wipes out CJ's tower, but spares Skittles/Duncan. He does not attack CJ and maybe that was because of her defensive position. Some survivors of CJ's tower attack and or try to rescue. Ink then attacks the water plant where some of CJs people may be located.

He goes to the Tower and kills Paul. However, he does not call in lots of others and he knocks on the door like a normal person when finished with Paul. In chapter 40 he kicks out the double doors of a prisoner transport van. My guess he could kick the door in, but he knocks on the door like a friend.

He laughs at Riley and Kilani after she tries to shoot him with an arrow.
