I think if you surround yourself with children it becomes difficult to hear the adults. It's too easy to drop a hot take and then dip out of the conversation, retreating back to safety, and never develop the tools needed for critical thinking or self-reflection.
You'll never have a chance to understand how the everyday people who aren't edgy internet pals see you, or why, or what that means for your life.
I mean your statement boils down to "is it possible for evil to do good" and I think the general consensus after a few thousand years of thought is "not really".
Initially I approached this concept as "can good do evil?" but after some reflection I think we have a series of choices and what we do in the moment is the only thing that matters. Good is only good if it does good.
If you want to tie religion into the issue, ask yourself "Is it possible to do evil in the name of good?"
