to look back on, to regret

みる(かえりみる) Pretty much only used in the sense of soul-searching or thinking about past misdeeds.
みる(かえりみる) Can be used literally OR figuratively, both with a good meaning (nostalgia, reminisence) and bad (guilty, reflecting on past misdeeds). Also, to consider the consequences of something you’re about to do (in which case, it’s used in the negative: he acted without thinking!).
