I can’t say I came to the same conclusions as you after reading that.
Also, for being an “unreliable” narrator he sure seems charitable to the people who ruined his life, no? I would expect someone with an axe to grind wouldn’t ask that they be forgiven.
i would certainly drop their names, and probably more illegal things if it happened to me.
but this isn't enough to draw conclusion. everyone is not Count of Monte Cristo, and can devote multiple years and money into revenge.
life is short,some people just want to move on.
