Just posting this as a seed for exploration: it is possible to curse someone, ideally an average joe and not someone deeply immersed in self-realisation, the occult, especually not an LHP type - by wishing upon them TOTAL enlightenment.
By which I mean, total perception of the harm they’ve done, the compromises they’ve made, the times (oh so many! lol) they’ve failed to live up the the standrards they blindly adhered to externally, and (most of all) by which they’ve judged others by.
I’ve done this - it works - it can wreck a mundane punter’s life by making them truly grok the extent of their deviation from their aspirations, their moral and certain axis mundi.
It’s kind of like this total perspective vortex concept - only, not funny sci-fi, actually just a hacking at the roots of where most people build their self-image and self-deceit.
I did it because I’ve also experienced this short sharp “calling to order” myself, which is why I did a huge working to clear all former regret and guilts - it is NOT fun to have to absolutely and undeniably realise how utterly crap, weak, lame, deluded (insert any other insult) you are.
If you’re really wanting to curse someone and yet still struggling on the perceived axis of the “love, light” thingy versus your will over all, look into this with your trusted divination methods etc., because it’s quick, clean - and ruthless.
