Then I think we may differ on whether we consider consent/agreement a part of kindness. I don't think it's that simple. I think an act can be kind but be delivered in an incompatible way. Asking someone how they're feeling after a breakup can be genuinely kind IMO, even if you didn't realize that that's the last thing they want to think about and asking them caused them to have an emotional breakdown that they blame you for. At this point I'm disregarding the tiktok thing entirely; I would still consider the million dollar gift to anyone an incredibly kind gesture, even if filmed without prior planning/agreement.

i think we are discussing separate points

OP commingled morals and kindness when his intent (now obvious to me after rereading) was to explicitly discuss morality of the situation.

You are exploring the morality of performing an action that violates moral norms (in this case, expectation of privacy)

We were exploring whether it is possible to be kind from an act if the end goal is obtain valuable exchange, off the act
