From the severity of the reactions you described and the way you talked about it (moment, mistake) I had thought it would be a lower murder or manslaughter charge. I think it's helpful for people to hear the never-ending punishment that a young person gets for nonviolent theft and recalibrate. Thank you for sharing.
That's a particularly bad offense for a software engineer. Wouldn't want to be in a meeting having to explain why I hired them if they mishandled data/access again.
