Luke Castellan

Luke Castellan is a villain in the Riordanverse. He was a foe and rival to Percy Jackson before his death in the fifth book.

Good Qualities

 * 1) He regretted betraying Camp Halfblood and Annabeth.
 * 2) He was an encouraging guy before he went rogue.
 * 3) His intent was understandable, though perhaps disagreeable.
 * 4) He is really good at fighting and hurting people.
 * 5) He housed Kronos in the fourth and fifth book, which is pretty cool.
 * 6) Backbiter, his sword, is an interesting and useful weapon.
 * 7) He is a good example for what Percy could have became but ultimately didn't. Percy had his fair share of resentment for the gods, but unlike Luke he did not betray them. Luke can perhaps represent temptation when not kept checked,
 * 8) He has shown to be a formidable leader and comrade.
 * 9) His last words were that he wishes no one would make his mistakes.

Bad Qualities

 * 1) In the movie he's generic and dull.
 * 2) He can be extremely annoying and hard to relate to at times. Especially since he has tried to kill Percy multiple times just because Percy isn't on his side.
 * 3) While his redemption is well meant and meaningful, the books don't give you much reason to believe he will.
 * 4) He is a traitor of the highest degree and brought immense grief to his family and friends.
 * 5) He is technically an adult in the series, so that means he was beating up kids five years younger than him and indirectly as well as directly killing people just as young. He did all of that while at the age where his actions are held accountable by him and him only. It's his fault he threw away the people he loved and perhaps he did not deserve them.
 * 6) He has a bully-mindset and has the stubbornness of an angsty teenager with extra adrenaline.
