So I gotta admit that these responses do decently to get into the headspace of those who though Adam was hot stuff. But they seem to put the onus too much on the show once more.
I recall doing a video talking about people needing to stop blaming shows when their head-canons aren't canon and I stand by it.
Adam's intro is not one that sets him up to be sympathetic, anti heroic or otherwise all that good to begin with.
He tricked Blake onto a mission where he intends to engage in wanton mass slaughter for shits and giggles, none of which she was aware of hence her surprise, has her act as his human shield, cackles maniacally when he gets powered up and then Blake end the trailer by escaping him.
That is his starting point, if one wants to make him more anti-heroic, or hell, heroic, then they have their fucking work cut out for them. Its not impossible, but its a steep climb and one rooted in headcanon.
Now, based on circumstances & context there's ways to do write a character like Adam differently. But stories and real world history also make clear that's not the only way these things can go, but the show isn't obliged to do that anymore than they were obliged to do anything one way or another.
But Adam stans did not realize or accept that and instead expected the show to cater to their interpretation which, even worse than trying to make Adam more nuances, just relied on ignoring or even somehow justifying all of the shitty, evil aspects of his character.
Then they got big mad when the show didn't do that and have spent the better part of a decade chucking a perpetual wobbly about it.
All while ignoring Blake, Ilia and especially Sienna who are characters that are a helluva lot closer to what they claim (At different tiems in different ways) to have wanted Adam to be.
IE, a Guilt-ridded redemption seeker, a person who just needs to be shown a way out, or a ruthless but heroic revolutionary; and I think its rather telling that they ignore them in favor of whining like stuck pigs.
