Someone tried to convince me of this the other day and did a horrible job of it.

But I'm curious, is there any truth to their viewpoint?

I'm not talking about the crazy ones, but are there any Chaos followers that could be argued to be "good" or have a rational reason for their beliefs?

ITT: Convince me to join the forces of Chaos.

EDIT: The title was a bad choice. Is there any truth to their viewpoint and do the Chaos gods ever do things for their followers beyond just using them as pawns and then discarding them after death?

It depends on what ones view points of good are really.

Define "good" please!

I updated the OP to be a bit more clear.

Well, they can make you a daemon prince - you essentially transcend and become an immortal being of the warp. Sort of. Or you can be a champion for ages and battlepiss on people with plague, or grow a Space Marine vagina, or just be a pretty fun guy to be around, like Kharn. You can even be a cosmic snek, like Fulgrim!

Yes and no Chaos isnt evil or good but Chaos marines just accept the disorder of the galaxy and heavily favor personal improvement compared to loyalists who they view has holding themselves back for little to no gain.

Are the guys who go around slaughtering defenceless civilians, using their skeletons as home decor and blood to summon even more monstrous beings the good guys? What do you think?

To be fair the Imperium isn't thaaaaaaaat much better when it comes to slaughtering defenseless people/xenos.

But this isn't about Chaos as a whole, but rather if there are any specific instances that break the norm.

Xenos aren't people, they are mere animals to be used if beneficial or exterminated if not.
