Tamlin is a good male indepth list:
Tamlin saved Lucien from being executed by his father, the High Lord of the Autumn Court, after Lucien refused to marry a noblewoman chosen for him. Tamlin then killed one of Lucien's brothers to get Lucien out and took him in as a friend and emissary, despite the risk. Provided care for him post-losing his eye.
Took in Alis and Her Nephews:
Tamlin allowed her to stay in his court as a servant and protector of the household and treated her with respect. Trusted her enough to share details of the blight and of his history with Amarantha.
Financially Supported Feyre’s Family and Healed Papa Archeron's Leg:
After taking Feyre to the Spring Court, Tamlin secretly made sure her family was taken care of. He sent them gold and provisions, ensuring they lived in comfort after years of hardship. All without fanfare or credit.
Tried to Woo Feyre Gently:
Tamlin didn’t pressure Feyre aggressively. He gave her space and tried to earn her trust with small kindnesses, like sending her paints and giving her freedom around the court. Playing the Fiddle for her. Writing Limmericks for her to help her learn how to read, after offering to help her more directly, but she refused. Showing her around the court (the rose garden, the starpool, the art gallery).
Told her: “Don’t feel bad for one moment about doing what brings you joy.”
Helped the Dying Faerie Who Lost His Wings:
Tamlin does everything he can to ease the faerie’s pain. He tries to use his magic to heal him, even though the injuries are too severe. He stays by the faerie's side, comforts him, and ultimately gives him a peaceful death.
Even knowing the curse might never be broken, Tamlin let Feyre go back to her family. He truly believed he was protecting her from Amarantha’s wrath.
Refused to Betray Feyre Under the Mountain & Engaged in The only consensual scene at all UTM.
Was the first High Lord to give a drop of his power to bring her back to life.
Without that act of selflessness, Feyre wouldn't have been resurrected as High Fae.
Promised to break her unwanted bargain:
And loses everything for it. To me this was a selfless, brave, and caring gesture. He saw how distressed she was over the bargain, while still UTM, and promised her that he would find a way out of it for her.
