Yes, ripe vs. unripe vs. somewhere-in-between will have different flavor. But if you're comparing two pods at the same stage of ripeness, they should taste pretty much the same. "Weird" is a pretty subjective term, so I won't address that. However, if your pods have signs something isn't right, don't eat them. Unfortunately, sometimes taste is the first thing that tells us a fruit or veggie (or whatever) is starting to spoil, so if you suspect something's not right with a pod, don't swallow it. Yes, it came off your plant, but pods can go bad while they're on a plant.
