Why does Ink (TOWTM) never attack the Mallers?

[Footbutt]

So, as i was listening to my 11th listen-through of the entire series, i thought of something:
why doesn't The One With The Markings (Ink) ever attack the Mallers?
i mean, there's no account given, if he did, but it seems like he only attacks "the good guys".

Notes:
i'm assuming Bill Roberts = The Man in the Pinstripe Suit.
He was a convicted Murderer, i think.
He must be really, REALLY smart (intelligent), in order to do all of things he has done.
His previous mental-health is either not a factor or has fueled his desires/plans for the turned-ones.

So i'm assuming that the Mallers never ran into Ink on their own.

the only time i can think of TOWTM and the Mallers being in the same place is during the first battle of the Tower, but even then, Ink's attention seemed to be fully focused on the Tower and not the Mallers.

So it is just his vague association with being a "theif, murder, etc" to the Mallers that are sparing their lives?
or is there something deeper.

Also, random observation:
When Samantha was being hauled away by the Zombies she says:
"Wait, no, Jacob. Don't!" or something like that. Who is Jacob?!?!
