[If it's of any consolation Knock Out doesn't like the idea of being controlled either, specially after what happened to Breakdown.]

I believe It's more about asking yourself if will be able to live with what you did rather than if it's ethical or not doing certain things. When we are at War we often find our ethics compromised.

[Knock out is free from bugs, mostly because he locked himself in his room and crushed all the little pest that dared to get in and bother him.]

That would be really really bad, indeed. If that's the case then perhaps I won't even have a planet go to back anymore.
