Passion... it lies in all of us. Sleeping, waiting, and though unwanted, unbidden, it will stir, open its jaws, and howl. It speaks to us, guides us... passion rules us all. And we obey. What other choice do we have? Passion is the source of our finest moments; the joy of love, the clarity of hatred, and the ecstasy of grief. It hurts sometimes more than we can bear. If we could live without passion, maybe we'd know some kind of peace. But we would be hollow. Empty rooms, shuttered and dank... without passion, we'd be truly dead.
Angelus about his obsession with Buffy.

Always so concerned with the human condition. It's no big mystery, man. They suffer, they die. That's what they're here for.
Angelus says

Angelus is the original form of Angel and the main antagonist of the Buffyverse, serving as the secondary antagonist of Buffy the Vampire Slayer and the main antagonist of Angel.
He was an Irish vampire and known to be one of the most sadistic and brutal creatures to exist. However, after having a Romanian curse placed on him, he was turned into Angel as retribution for over a century of tyranny as a soulless vampire, whenever Angel experiences true happiness, he loses his soul, thus reverting back to his original form. He is the archenemy of Buffy Summers.

Early life

Before becoming the vicious vampire Angelus, he was a human by the name of Liam, born in Galway, Ireland in 1727. His father was a linen and silk merchant of some wealth. One day, at the age of 26, after a night of his usual drunken debauchery, Liam got into a fight with his father, who declared that he was wasting his life and slapped him. Liam responded that he was what his father had made him, and left their household in a rage, his father doing little to stop him, despite his obvious grief at his son's harsh words. After a tavern brawl, he was kicked out, and followed the woman - the vampire, Darla - into an alleyway. She promised to fulfil his dreams, and show him a whole new world, and sired him, turning him into a vampire.

Liam and Darla went about killing every single inhabitant in his home town, until finally, Liam decided to move on, but not before killing his entire family. He took the name "Angelus", seemingly inspired by the fact that his little sister believed him to have returned to her as an angel, shortly before he killed her.

Angelus and Darla traveled the world for decades, wreaking havoc wherever they went, and creating a reputation as the most vicious and dangerous vampires in the world. Angelus had a gift for torture, both mental and physical, and enjoyed nothing more than using his dark talents to create works of "art", in the form of brutal murders and tortures.

21 years later in May 1764, Angelus and Darla killed the wife and son of Daniel Holtz, and turned his young daughter into a vampire, forcing him to kill her. Holtz then devoted himself to capturing them, and chased them across Europe, managing to kill almost 400 other vampi
