So you're saying that nobody realized the effect the suit was having on Nanosec, and the Autobots are still culpable? Like you said, they don't even understand age, being robots and all.
.....Did you see the episode? "White hair in humans is usually a function of age", as quoted from Prowl. Which led Bumblebee to his coldhearted act of driving Nanosec to retirement. Not to mention the countless times that the Autobots commented on Ratchet, and him being halfway into the Matrix already.
So, yes, The Autobots knew about what 'age" means, even in a human context. And at least Bumblebee also knew that the suit was affecting Nanosec, and aged him rapidly. Knowing that, he still lured him with the intent to burn him out. That is cold. And unless you're what they call an 'anti-hero', not right either.
Did *you* see the episode? There was a big "aha" moment at the end when everyone realized what was happening to the guy. Prior to that point it was all just "hmm that's odd". You have to demonstrate that Bumblebee knew specifically what was happening to Nanosec in order to support your view. I don't think that is demonstrable.
