Yes or no what kind of damage is there or you just have to take care of yourself
wanted to do it on a linux laptop
No, of course you can't. Risks are various viruses that can eat your hard drive and / or get caught. But the latter is very unlikely.
Legally no. In practice, however, nobody will be interested in it.
Just make sure you don't get a virus.
Cracked sounds illegal, you don't think so. So I allow it for once.
If you want to make yourself a criminal offense, then yes. But generally no. It is generally forbidden to download cracked software. Leave it!
So it's not legal, but I don't think anyone cares. You are more likely to install a virus.
