Someone who is starving and steals food (under pressure) is different than someone who isn't starving and steals food(not under pressure). The person under pressure is probably not a thief under normal circumstance - but he has to steal to survive.
It's amazing how anyone can go through life and think about it so black and white. This thread is rife with confirmation/survivor bias. We're talking about going to an office and creating some widget in 90% of circumstances. Most of the "pressure" is made up. This isn't war or the jungle.
The fact that it is often more ugly than we wish, does not change it.
Also does not negate the fact that prep work is worthwhile to form habits and counteract the base reactions.
