Not being a good fit doesn't mean not safe or competent. Every airline has turned down "tier one" heavy hitters from all backgrounds, including LCA's, fighter pilots, pilots with a million type ratings, Air Force 2 pilots, decorated fighter pilots, etc. That doesn't mean an airline that turns them down this they're "untrustworthy" or "scums". Airlines all have a set of criteria of what they're looking for that goes far beyond safety or trustworthiness. Lots of what they try to assess is based on personality and cultural fit.

Also, every airline hires pilots who weren't hired at other airlines. The interview process is never perfect. Some good pilots slip through the cracks and don't get hired who should, and some "future one percenters" sneak past the process and sometimes even their first year. But a flow guarantees that an airline is forced to take 100% of the pilots that won't be a good fit at an airline, and that's why there historically have been very few flows compared to being hired by interviews. That's just how it is, and that doesn't make it a dramatic injustice like you're implying.

Going full emo with the hyperbole and trying to turn it into something it isn't is probably related to some of that. No airline would ever hire anyone who they knew that, if they didn't hire them, they would act childish about it.
