I think it's time for a refresher about what a "trickster" is and what makes a character or deity one.
A trickster is a boundary-crosser; an entity who highlights the rules and conventions of society by calling them into question, usually with their actions, and usually by breaking said rules and conventions. This helps us assess why these rules are in place and if they even serve us.
Because of this, tricksters tend to be transgressive and subversive. Sometimes this can be very delightful and other times can be very uncomfortable, even repulsive.
"Trickster" is a function, not a personality type. Sure, many tricksters are cocky and possess a devil-may-care attitude, but so do other beings who aren't tricksters, and there are many tricksters out there that don't have these personality traits.
Tricksters don't exclusively deal with absolutes. Everything they do changes depending on the situation they're dealing with and the goal they're trying to achieve. And unfortunately, this is what many people seem to misunderstand.
For example, I often see people say, "Tricksters are never trustworthy," or, "Tricksters always have ulterior motivations," when the truth is that tricksters are situationally trustworthy, and tricksters situationally have ulterior motivations.
Tricksters are capable of being selfish or selfless, helpful or harmful, constructive or destructive, kind or cruel, etc. all depending on what it is they're trying to achieve. We may not always know what they'll choose because they're operating at a higher level of meta than we are.
This is the nature you're dealing with when dealing with a trickster. They're not "secretly a villain" or actually an "unconventional and misunderstood hero." They're a trickster, and that moral gray is what you're going to get when dealing with them.
