Why shouldn’t I rugpulling?

Im not sure how should I say this. But I have been scammed for sometimes. I see a lot of shit project static website making thousands. I can do 10 of them in an hours or 2. And this makes me wonder, should I do the same. From my perspective, launching a coins and investing in a coin is basically making profits from someone else lost. Is there a moral difference between this? If I tried rugpulling this will be my first time.
