Being cowardly and being scheming are not the same thing. Being scheming is about having a plan and executing it. Being cowardly is about being afraid and acting based on the fear.
I agree, but I think both occurred. they had a long-term secret plan and tried to execute it (a scheme), and then when it went poorly they acted based on fear (or possible just complete disregard for the truth and interests of others).
