I wouldn’t recommend learning to draw from scratch digitally no matter what software, but if you’re not a complete beginner and you’re willing to experiment with its functions, I don’t see why not. There’s a large helpful community and lots of tutorials too.
The thing is, other shitty people care. They see how we treat dead shitty people and, because humans are irrational, see it as a reward for their behaviour in life. That’s also why I’m against the notion of not speaking ill of the dead - no, people need to realise that they won’t be respected when they’re dead if they were shitty.
I know it doesn’t matter, rationally. But humans are weird and care about what people will think when they’re gone.
