Tell us you're joking, please.
If not, then consider how you'd feel if someone came into your home/apt. and took, without your consent or knowledge, several things that we're of value to you. Would it please you to be held up and robbed of your wallet & money?
Bottom line: treat others the way you'd like to be treated.
If everyone acted like you (egotistically ? creating hardship for others and dissolving the basis for trust), we'd be up shit creek.
What goes around comes around. Your actions will catch up to you ? if not in the form of getting caught and punished, then in your ability to form any kind of long-term, meaningful friendship with others. My guess is that there's already a problem there.
