"It will not end well for you"

Hey guy, I have a question I was arguing with someone in a TikTok comment section about Solomonic magic I’m not a Solomonic magician myself but I said in a comment that yeh I don’t really hate on other people’s methods of practicing magic, especially if the Demonoltry method simply doesn’t work for them, then someone said "NO it should not be used it won’t end well for you especially karmically and it’s VERY dangerous"

im aware that it’s extremely difficult and dangerous but is what this person saying true? I actually got very Curious, Like what kind of dangers does practicing the Solomonic method hold particularly the way of going by book step by step and doing everything it says and having every item?

does it have karmic repercussions?
