>>43321713Your honor and selflessness are where a paladin finds his strength. It's the fuel that allows him to stand in righteous defiance against evil and burn back the shadow. There's enough evil in the world to where even the noble paladin needs to tolerate the grey of his comrade's actions for the good of the innocent. Ultimately, you're not there to be a policeman. You're there to serve as the example that a truly just, truly good person cannot only survive, but succeed in the hateful world you live in.
I once had a cleric/paladin who was abducted and forced to help an evil party to serve as their group healer. He was completely lawful good, in a party that was delightfully evil (admittedly, the players were extremely mature, making this easier to pull off). He never redeemed them, never preached to them. He helped them only when their goals were not directly harming people. He even developed an affection for them as comrades. When pressed, he would point out he could not help them with his healing if they reveled in slaughtering anything more than monsters.
Meanwhile, he slowly tended to the downtrodden in his off time, learning the basics of magical obfuscation from the group's necromancer. He gathered a small, secret group of people (mostly former slaves who he purchased with his money) and set up a small chapel in a slummy tenement building. He was able to set up anti-scrying and sneak in provisions to his growing flock. Only his party had any idea he was a paladin. He had to be sneaky and discrete, never letting on who he was, what he was or what he was doing - not even to his own party.
He ended up betraying that party and pulling a major victory for good as he did so.
As long as you act with honor and compassion and put the safety of the innocent first (or your oath), you'll be fine in a group of morally grey.
