I have a question about Smith. I want to know if I missed something.

After meeting in Jane's house, Smith runs away and we see Bertram trying to kill Smith using Oscar.

Who wants to kill Smith?

A) RJ orders Bertram to take care of Smith. In this case, it makes no sense as RJ could easily put Smith next to Haffner and Stiles and kill him.

B) Bertram wants to kill Smith. But why? Bertram has no reason to kill Smith. It is not that Smith is gonna talk or anything. They even work together (McAllister-Bertram-Smith meeting in Bertram's office)

Can someone please explain me why there was a target on Smith?
