Shit, one of my first rounds as security I ended up taking the ion rifle to try and detain a suspect at departures, I had no fucking clue what it actually did at the time, I killed/wounded about 5 people with prosthetics and a destroyed couple synths. Everyone does dumb shit, it's part of the learning process.
Just don't worry too much about the traits you give your character, what matters more is how they're used. So long as you don't go overboard on things and show restraint, you'd be surprised with what you can actually make work. If everyone had generic, standard characters the server would be a much more boring place. That doesn't mean everyone should be a burner clone that gets wiped and reset every 24 hours and increases productivity by 25%, but having some out of the ordinary traits isn't a bad thing by default.
and every one of my characters is a dirty snowflake, so much so I'm scared to take the test
