Even when playing my "good" character I find it hard to resist the urge to steal everything that's not nailed down. Would be much, much poorer if I did.
1. Use stealth-boy
2. Engage sneak
3. Steal everything (same karma outcome)
Also, skitzor, silver rush lets you get off with stealing one thing and one thing only, after that it's "melt you down into goo" hostility.
