Love

Love is power that gives you the ability to do very great things. Someone full of hate cannot understand love.

Love Before 1980
In 1899, Albus Dumbledore's love for his brother and sister pushed him to turn against his old friend and attack him, finally destroying him in 1945. In 1977, James Potter's love for Lily Evans changed his character a little, by the fact that he stopped hexing people just for the fun of it.

Love In the 1980s
In 1981, Severus Snape's love of Lily Evans pushed him to join the Order of the Phoenix, even though he hated her husband. In that same year, Lily's love for Harry protected him against Lord Voldemort.

Love In Harry Potter's Life Time
In 1992, Harry Potter used love to defeat Professor Quirinus Quirrel. Also, in 1993, the love of his sister, Ginny, caused Ronald Weasley to head down to the Chamber of Secrets to rescue her. In 1994, the love of his godfather enabled Harry to rescue the former. In 1995, Harry used love to be able to escape Lord Voldemort's wraith. In 1996, the love of Sirius again helped him, when the grief after his death pushed Voldemort out of him. In that same year, Dumbledore ignored Harry, thinking that he'd be less tempted to go down to Ministry of Magic, because "I cared to much about you." In 1997, Harry's love for Professor Albus Dumbledore pushed him to attack Severus Snape with one of his own spells. In that same year, Draco Malfoy's love for his family pushed him to attempt to kill Dumbledore, even though he really didn't want to. In the end, Harry's love finally destroyed Lord Voldemort once and for all.

Love and Magic
Love Potions, like Amortentia, and Entrancing Enchantments are meant to create love, but don't because nothing can create love.
