Truthfully, its not "evil", but it is still "wrong".
Imagine you make something and you expect that something to be your sole income.
A friend goes out and buys one copy. Now he gives it to all his friends, lets say ten on them.
You have been paid once, while eleven people have enjoyed your hard work.
You have to eat instant noodles tonight because you can't afford anything else. This is hardly "fair" in your eyes, or at least, it should be.
i'm not saying its right nor proper, i'm vetoing the view of it being "evil".
and for the record, people do share them unknowingly that its piracy.
family, friends, and even just some nobody, they'd just simply share it because they liked it.
i mean imagine it, your dad bought a movie and decided to watch it with your entire family, this is also piracy.
its even worse with images.
like it? post it on facebook or somewhere else.
it doesn't matter if it had a watermark or whatever, they'll still share it with others.
the very concept of "sharing" is piracy.
even if its through distribution, streaming, or just watching it with others.
simply put, passing the "information" to another is piracy.
