How can I be ultra violent?

I do want to improve, but I'm also wondering if I can start from early on playing gambits or sacrifice openings to make risky / uncomfortable situations for both players. I think the difficult positions that arise can make both players look for tactics right away and feel the rush even in 15 + 10 games.

No, it's an OK way to teach yourself tactics. You might end up losing quite a few games because you don't have the skills yet to cash in on any tactics that do come up; but as long as you care more about creating learning opportunities than about scoring points, gambit play is fine.

Will this mindset slow, or even worst, stop my progress as a beginner?
If it brings you enjoyment playing this way, then go for it.
We all learn differently, and while your way may not be my way. That doesnt mean it isnt a good way to study. Having fun is half the battle.

Find your own style and try to win and improve with that style.
The important thing is to also have fun!

I rocketed my rating with gambits, but not the crazy ones (like halloween's, danish, etc).
Just the ones where if your opponent played stockfish-like, you'd still have a completely playable position, but still have traps where your opponent can go wrong.
EXAMPLES:
Evans gambit, Scotch gambit, Max Lange attack (gambit a pawn).

Did you feel a higher rush playing gambits than before?

YES! they are fun but for a beginner you will probably return to a more stable and in control opening soon because they are not for everyone.

I would joke about drugs but that's not appropriate. you get my drift?

I just started playing chess. Is it okay if I play gambits and sacrifice openings if I want to play very aggressive games? Even if I lose, I don't care about winning, but making fun and intense games.
I think keeping unbalanced risky games keeps both players in high adrenaline and sweating while both are running out of time. This uncertainty, call me a masochist, feels better than having a slight advantage in the opening. Is it possible for a beginner to make progress if he or she chooses this path?
Just tactics and risky openings from the start; putting both players in uncomfortable situations from the beginning. Someone told me to try the Jerome gambit, The Fried Liver Attack, The Danish Gambit, Halloween Gambit, etc.

Play positionaly, that requires true skill.
Why have skill when you could have fun
