Watched his mother die in a fire at age 8 that had him separated from his twin brother (the only family he had left) for years, reunites with his brother only to watch him willingly plummet into hell and sliced Dante's hand to prevent him from saving him from falling, later down the line ends up KILLING said brother who was tortured and brainwashed by the guy who hated their dad and he didn't even KNOW that was his brother until he'd already landed the killing blow
