Slaaneshi sect

A Slaaneshi sect proposes you to join them. As long as you serve them with fidelity and devotion, and agree to perform the deeds they request from you, they will invite you in rituals that will lead you to live the most intense and extreme experiences you ever dreamed of - food, sexuality, entertainements without limits.
What do you do?

I report them to the nearest imperial authority. Even if I was interested in that sort of thing, it's obviously a trap, and most definitely not worth a after life of eternal torture.

"Is this testing whether I'm a replicant... or a lesbian, Mr Deckard?!?"

I'm morally bankrupt and looking for a good time, so I'd take then up on that offer

"Good choice my follow imperial citizen, the empire needs men like you. Anyway, can you still follow us in a other room..."

The only pleasure I need is that which I derive from venerating the Emperor and striking down His enemies

Aight, but no butt stuff.

YES, BROTHERS AND SISTERS IN THE DUALITY! TAKE ME IN YOUR WLECOMING ARMS, BATHE ME IN THE BLESSINGS OF HER WHO THIRSTS AND PUT AN END TO MY MISERABLE EXISTENCE! GIVE BEAUTY AND MEANING, GIVE ME ASPIRATION THAT WILL MAKE ME FINALLY WHOLE! PRAISE BE THE SNAKE, PRAISE BE SLAANESH THE DARK PRINCE!

Probably, I'm more of a tzeench or nurgle kind of guy. Depends on who approaches me first you know. As long as it's advancing chaos im down.

Please, the only pleasure I need is from firing a bunch of guns. LOT'ZA O' DAKKA you might say
