Personality
Except, all he ever wanted was to become Thor's equal and gain his father's approval. Despite his animosity for his family, Loki was very protective of his younger sister, Freyja. However, he was forced to fight her when she didn't stand down, but he never had the ability to kill her like Thor.

He also still loves his adoptive sister, Freyja and fought in her name when he thought she was killed.

Loki also believed humans were inferior to Asgardians and that he had a right to rule them. He also believed he was immortal (without realizing thwart Asgardians and Frost Giants line and die like normal "mortals" do). Loki disapproved of Freyja 's relationship with ex - Ravager James Quill and mix need Thor for falling in love with a human woman. However, he did save Jane Foster when they were in danger and Saved James from falling off a cliff.

Thor
Loki was best friends with his brother Thor. However, Loki was jealous of his brother and only ever wanted to be Thor's equal.

Freyja
Loki never had animosity with his younger sister, Freyja, due to her avoiding her father most of her life and instead learning magic from their mother, Frigga together. However, he mocks her once, telling Freyja that her compassion and attempt at peace-keeping will be her undoing. To prove him otherwise, she fights him in battle while also defending Thor.

Due to her strong bond with her brother, Freyja felt Loki and Thor fighting each other and felt her brother pinned down on the ground.
