I like it as a Millennial puritan sort of name, like naming your kid Riker, Indi,
Neo, or Cloud. It's satisfyingly weird. It has a good sound, I can see why you enjoy it. That "mpt" part is good. Imagine going by
Red and when people ask if it's a nickname you tell them it's short for REDEMPTION! I don't know about you guys but I'd seriously love coming across that irl.
I think on a boy it almost works, on a girl it's way too preachy and has a lot of gender baggage.
I honestly think it needs a middle name that is as ridiculous or pop culture-y, because pairing it with a classic name like
James or
Daniel takes it way into Bible-thumping territory.
I think it'd also pair well with a surname-name for some reason. And extra points if it's also from pop culture, just go for it I say
