1- You don't know why I put the money there
There is no clever reason to do so.
2- You don't know how much I put in there
Any amount is too much.
3- You don't know how much I withdrawn
Even if you withdrew money, it doesn't make it a wise decision.
4- You don't even know if I lost a single satoshi with it
Even if you were fortunate enough to gain money, it would still have been a stupid risk.
5- You don't know me, how I live, where I live, what I do for a living or how much I earn
I have a few £50 notes in my wallet now. I could take them out, set them on fire, and I'd never feel the difference or miss the money. It would still be a completely stupid thing to do, would it not?
I can't say a decision is stupid when I have no data whatsoever on why the decision was made, and you shouldn't also.
I don't know why you are burning the bills, so maybe it isn't stupid after all.
Things aren't as black and white as you want them to be.
