Dumbledore is obviously a gay. At most, he is in love with the person who cannot even be named, and it is unlikely that he will get involved with his mother;
The famous Quidditch player James Potter is undoubtedly a brainless gangster. As his mother Lily was the school beauty of Hogwarts back then, her taste and vision should not be that low;
Severus Snape was a sad man trapped in love and obsessed with love. He must have become like this because he was unable to be with his mother for various reasons.
Albus Dumbledore was more wary than protective, more concerned than helpful, more restrictive than nurturing. Rather than saying that he is the student he cares about most, he is more like an important hostage under his control.
James Potter is probably just a taker, and his role in the whole conspiracy is probably insignificant. Perhaps only Severus Snape, who "loved his mother far more than he did, but tragically failed to even qualify as a Panzer", was full of jealousy and resentment towards him. Everyone else who had witnessed the unspeakable black history of Hogwarts was full of contempt and disdain for him.
Severus Snape is obviously not an incompetent person. His aura as a potion master cannot perfectly conceal his profound knowledge in the field of dark magic that is almost unmatched by others - and he is definitely not a coward who gives up easily. Helplessly giving up but persisting in another way without any regrets can only show that the person who defeated him to win his mother's heart can only bless him when he loses.
Then:
Who is Harry's father?
Where is dad?
