This sadly reminds me of one of the days I "ruined my life". My base degree was aerospace engineering but my main focused more comp/sci towards the end. When the houthi/u.s engagement restarted a company here in the states took a contract to change a $1,000,000+ "smart" missiles to a "smart" firing system that launched ~$10,000 munitions. I quickly saw where this was going and how fast we were progressing and also saw a request for how it could be refitted for strike instead of defense. I left the next day. Didn't have a job lined up. Found something at nearly 1/3 the wage 2 months later. Still felt better about my decision having eaten near nothing and scrapping by.

There is a difference between knowing which side is right or knowing murdering innocents is worse than meals.
