alright let's start nice and easy what happens if you are accidentally tricked or baited into betraying the imperium you haven't necessarily drank from the chaos kool-aid but due to chaotic manipulation you now find yourself at war with the god emperor of mankind this is actually quite an easy situation to recover from depending on who you are if you are cannon fodder being used as a pawn by your lords and commanders even if your army surrenders and admits its transgressions and regrets it you'll likely still either be shot in the back of the head or sent to work hard labor until you die your best bet would be to desert the traitorous army and gain a new identity or a defect to the imperium mid-war and give them intel while saying that you are always a loyalist an example that compares to this is when a number of goodra knight riflemen were commandeered unknowingly by the forces of chaos when they realized what had happened they tried to escape and some of them were able to do so they were treated with respect by the imperium and allowed to fight for the emperor against chaos in the following battle without consequence if you're a space marine that finds yourself on the wrong side like how the lamenters did during the bad dab war upon defeat your chapter will be humiliated bankrupt and then heavily interrogated if it is shown that you were just genuinely mislead and still thought you were serving the emperor then your chapter will likely be sent on a near suicidal penitent crusade in order to make up for what you did after the bad dab war where the lamenters got their PROFANITY_TOKEN kicked in by the minotaurs they were allowed to continue their existence in the form of a penitent crusade so surprisingly going to war with the imperium isn't a one-way trip to hell as long as the source of your betrayal wasn't corruption or heresy you can generally be redeemed with a slap on the wrist what if you betray the imperium and join chaos or become a renegade can you come back from that well it really depends imagine chaos as a pool of acid you dip your pinky in ouch pull it out you now have a burnt pinky but you're pretty fine overall you dip your foot in big ouch your leg huge ouch eventually you won't be able to pull yourself out of the pool same with chaos the more balls deep you go the harder it'll be to pull out however if you are a renegade fighting in a chaos warband and you witness something PROFANITY_TOKEN like an emperor's children's space marine raping a sausage dog or some PROFANITY_TOKEN and you think to yourself what the PROFANITY_TOKEN am i doing and this is PROFANITY_TOKEN and you decide to try region the imperium as long as you don't have like tentacles and PROFANITY_TOKEN it's actually not that hard you have two options option a would be to find a loyalist chapter with the same gene father as yourself and basically ask to join and apologize for being a heretic if they're a chill chapter and don't have any librarians nearby that can mind rape you and discover your heresy then you could be sweet but
