All this blaming people is fun, isn't it? And I can see that it's really working out for you. But maybe it's time for another approach. I have a policy at work: everything is my fault (except on Wednesdays, then it's Malachi's fault because she was with her father at work one day and volunteered to give me a day off).
I think we can use that here. Please blame all your previous squabbles, inefficiencies, etc. on me and/or Malachi. Then fix them. I think you'll all feel better about it.
P.S. If you could try to use logic and reason as you go about fixing things, I'd really appreciate it.
