The Worst Thing Jonah Byrde From Ozark Has Done

So what exactly did Jonah do in Season 4 of "Ozark" that was worse than anything he's done to date? He betrayed the Byrde family in high fashion by going to work for their mortal enemy Darlene Snell (Lisa Emery). That's right, the youngest Byrde actually became the go-to money launderer to the Lake of the Ozark's ultra-violent and unpredictable heroin kingpin. And yes, that's the very same Snell who terrorized Jonah and shaved his head a couple of seasons prior in a thinly-veiled threat to his parents.
Jonah's turn to the darkest of dark side in the "Ozark" landscape was shocking, to say the least. While some might write it off as Jonah technically going to work for Ruth Langmore (Julia Garner), it was never not Darlene calling the shots in that arrangement. In the end, Jonah even sealed his betrayal by detailing to Darlene the role his parents played in the death her puppet Sheriff Nix (Robert C. Treveiler).
How could Jonah do it, you ask? The truth is, the kid has been legitimately reeling since the death of his Uncle Ben (Tom Pelphrey), and learning that his mother Wendy (Laura Linney) was directly responsible for Ben's death. While that doesn't entirely excuse the depth of his betrayal, there is at least some semblance of reason behind it, when you consider how such an event would traumatize a kid of his age. And even with Darlene now officially out of the way, the question still lingers regarding whether the Byrdes can bring Jonah back to the flock before it's too late.
