Friend did not take ritual to become Zevist seriously?..

[Rey Villarreal]

I don't believe he did it on purpose, but was utterly nervous about it, after signing his name in blood, several minutes after, internal cuts has arisen from his skin as slashes, he awoke to gashes over his head/body. His left eye has gone blurry, with a grayish cloud. He states to have seen a demon trying to touch him. He's visioning things,

What can he do to redeem himself or cure this mistake?
