The actions I was referring to were the times when Flowey used his powers for good. And Flowey at least had good faith, even if lacking actual compassion, and he made actual efforts to feel said compassion.

We don't see evidence that Chara even tried to be compassionate after their death.

If Chara was in the same situation as Flowey, then they should start being good, before their own apathy turns them evil.

Flowey turned evil because he eventually decided he just wanted to see what happens, without caring about anything else. And without any actual feelings of compassion to come in and snap him out of it, well... He got stuck that way.
