I actually thought it kind of made sense, when Matt explains it. Lady B was trying to get Kingsy after Matt for the umpteenth time, so they preempt her.
However, Fisk is a bad person and he mostly works with bad people. When Matt and him teamed up to escape prison, Fisk tried to release Bullseye. Now that they're working together again, he does something similar. And the cop who was killed as a result? Matt's gonna freak.
Still think that Lady B and Master Izo are trying to trick Matt though..
