Shadowrun

My characters are organizing an extraction of local (country) MCT head of security. He is Japanese, raised by the corp from birth, but not completely beguiled as his son is an orc and he had to pull some levers to get him into school etc.
He's aware of extraction and agreed to it.

But the twist is that he decided to get extracted because he's taking the fall for a secret lab getting blown up in the middle of MCT office campus. So in a way he was made responsible for actions of some shadowrunners and now he's hiring (technically it's his mother organizing this but that's a detail) another ones. I think that can evoke some ambivalent emotions.
They are going to meet in secret soon to get some of his blood, pass the details of the plan, etc.
What are your thoughts on how to roleplay his attitude towards the characters and the whole thing?

P.S. He doesn't know that but, of course, it was our jolly bunch of psychos that have blown the lab up.
