Probably a weird and slightly scrupulous sounding question, but I’ll feel better if I get opinions from others so I’m going to ask :o
I draw for people, and a person on a website asked for me to draw them something for another website. The drawing was for a contest, and I had asked them if it was against the rules for me to draw them the thing for the contest. They replied that they " “prefer” you use your own, but it isn’t necessary. Just to avoid hassle is rather not explain the situation, but it doesn’t violate any rules." Even though they said this I still suspected that it was against the rules, and drew for them and took payment (was only $5, but) anyways.
Just now I looked at the rules for the contest and saw it does say it must be created by the entrant.
Would it be a sin? I told them I no longer wanted to draw for them which they accepted, but I wasn’t sure if it would be a sin.
If so is it venial? mortal?
Should I donate the money I took? Unsure what to do!
