You found a cure for psoriasis

You cannot save the world.

People suffer every day everywhere around the planet. It'll never stop. P is just one area and there are of course many medical conditions that cause suffering.

So, you could argue that giving away the cure will help P sufferers, but it will only help those with P.  But with all that money you'd be taking off the giant corporates, you could give it away to other medical sufferers.

Where does it end ?  Can you save everyone ? No, is the answer

Indeed that is right, but how much are the giant corporations making every year, on " control drugs" and as soon as a cure is found that revenue will stop and it makes £100 million look like chicken feed .

but since joining here I have one cause that I can help, and if I had that cure, it would greatly help a large portion of humanity, who knows my cure may well work on other autoimmune diseases, in which case it's even more important than money

Helping animals is a good cause and as you say you can't help every cause, but there's animal and human suffering going on everywhere and even £100 million would not go far.... Look at the dog eating festival in China ....
So I still maintain patent it and give it out free.
To my mind money brings greed and more suffering
