Well, this isn't really the forum to ask that, but to answer your question, absolutely not. Some of the best artists know NOTHING about scales, modes, etc. (well, to be fair, many discover it for themselves by listening, learning, and playing other people's music, but they don't all study theory websites or books, or that sort of thing).

Some do, some don't

I personally play by ear, but I know a small bit of theory.

Depends on the genre as well. Those who play progressive metal mostly have a little or great knowledge in theory, scales and modes. In thrash metal, not so much. Rock and metal generally rely on the minor pentatonic scale.

listen to a slayer solo. does that sound like using theory?

Why would you listen to slayer???

Sorry I thought it was the right spot... But I always thought if you use scales it'll sound like you know what your doing on an emotional level to the audience rather than playing as fast as you can.

Even if you don't know anything about theory, everything you do musically relates to theory in some way. Music theory is how music is explained, not a set of rules.
