so recently I listened to an great warhammer audio book. with an guardsmen called regan Antigone. it confused me.

1. the space marine that was supposedly "heretic" but helped the guardsmen hold off the chaos heretical onsluaght

2.why shoot a hero of the imperium when his thoughts an actions were purely in duty to the emperor and imperium.

I mean I know its warhammer, heresy=death by all accounts but still confuses me sorta.

my point is whats so bad about this mystery space marine who was wearing armour un desecrated an protected the city from an horror?

(anybody know any other audio warhammer 40K books?)
