Is orchestrating Garma's death Char's most wicked act?

Yes, yes, okay, I can already hear people saying that attempting to drop Axis on Earth and potentially killing millions while displacing the entire rest of the earthnoid population is obviously a more evil thing to do, but I want to consider a couple of things. First, if consequences matter more than intentions, then we must consider the fact Char does not succeed at dropping Axis and ruining millions of lives, while he does succeed in getting Garma killed. If intentions do carry some weight, then we must also consider that Char's intention with Axis was not to vindictively kill people, but something he thought was in the best interest of both humanity and Earth in the long run. Distorted as it may have been, he felt he was doing a harsh but necessary act to force humans to be better. Meanwhile, his intentions with Garma were wholly manipulative and cruel.

It's something I want to dwell further on. Although he does it for some sympathetic reasons of wanting to gain the approval of his father and wanting to "prove himself" as the young member of the family, Garma does willingly serve in a position of reasonably high command in the Zeon army so we can't exactly call him innocent. That said, aside from Mineva he is the least culpable member of the Zabi family in Zeon Zum Deikun's death, having been a child no older than Char when it occurred. Char knows this, and does not care. He intentionally misleads Garma to force a situation where Amuro and the crew of the White Base do Char's dirty work for him, and radios Garma to gloat about the fact so that he knows he was betrayed.

This strikes me as a supremely cruel and cowardly act on behalf of Char, both for the underhandedness with which it as done and the fact that it represents a betrayal of what was at one point in his life a genuine friendship with Garma. Garma does not truly bear blame for his Father's death, but Char knows that killing Garma (And I think it's accurate to call Char Garma's killer even if he didn't personally do it) will harm the true perpetator, Degwin Sodo Zabi, in a way nothing else can. He forsakes his friendship with Garma and reduces him to a game piece on the board of his revenge, ending his life for a crime he, by Char's own self-admission, was not truly complicit in.

To me, this moment represents Char at his absolute lowest, morally. You can argue that he's an outright war criminal by the end of his life for many other reasons, and perhaps you would be right, but the personal level on which this particular act takes place simply resonate so much more strongly with me. I'm curious to hear what others think.
