Being impulsive is a very bad idea in magic. Here is a tale.
It's been of note to several people --Violet Cabra has a few essays that go into detail about it from the American Neopagan perspective-- that the moral compass in many esoteric circles is dubious at best and it has the labels flipped to convenience at worst. This tends to be worse in esoteric groups and practitioners that work at the beginner level and requires no skill or specialized training. I suspect this is because at that level you are not really aware of what it really is what you are doing and you need a degree of attention to see the effects in one's life due to the limits of power you can draw from the sources of natural magic alone, among many other things.
For that reason in such groups, specially online, there are a lot of the suggestions to deal with inconvenient situations and people that amount to cursing them or straight up engaging in demonolatry. I, unfortunately, have had to deal with such people first hand at least a couple times. On one part because I have trouble keeping it shut, and also because I have a soft spot for eccentricity.
One of the reasons why I think this happens is because power really can be inebriating and soon enough witches, in the old christian sense, start thinking they can pull themselves out of and change any situation they like for their benefit without facing the consequences --until they don't.
The reason for this is karma, in the traditional hindu meaning. Whenever you curse someone, it goes deep into your sanchita karma, the back store karma you will deal with once you deal with all the karma that gave rise to your current incarnation, which is called prarabdha. Most people don't finish that process and make bigger stores of sanchita. Prarabdha is stored on the astral while sanchita is above that. That means, yes, you can cleanse your aura of the immediate blowback effects of your curse but you can't touch what went into your sanchita and deep within your being. You might wear a glove tu punch someone, but that doesn't stop you from becoming a jerk. So you might happily prance around until you learn the hard way the dynamics of karma don't agree with you and find yourself in a world of pain.
You see, karma is a sort of memory that holds you in place, the natural state of the soul isn't like that so we are here in Malkuth, the physical world, because of karma, you get rid of all of it and you are gone from incarnation --you don't have enough dense substance to hold into a body. That's the reason why some enlightened beings deliberately have a passion or a vice that generates enough karma for them to hang around.
There's a thing to karma though, and that is that it comes in a linked chain. If, for some reason or another an event or situation pulls on that chain, and suddenly your karma for this life receives an incoming delivery, it better be good karma or you are seriously screwed.
This happened, as I received word, to two persons that sent nasty curses my way. The first, a trained witch with full intent and awareness of cursing me violently seems to be in an unpleasant state after 3 months of sending very nasty energy at me every full moon. Ironically that is, because I told him that he shouldn't be suggesting newcomers to curse people, which he didn't like and down he went. The second one, an unintentional and untrained witch on an ego trip spent months on end fuming and fussing about me leaving her as my romantic partner --she got mugged at gunpoint and later developed hepatitis. The liver being the house of the will, I was not surprised it's misuse sickened the physical organ.
So folks, please don't go about cursing even though it really might look like a great idea or seems it has gone without consequence, it will come this life or the next. In a world of spiritual bullies also, please be protected, there's nasty things being thrown around all the time, even in non magical circles. If you can, an honest prayer of blessing for the perp helps cut the connection if you find yourself in that situation.
