Paladins are expected to be courteous and noble, in a sense. What reason they give you after they notice you're evil, and refuse to travel with you, is one thing - but how they put it is another. It is not very paladin like to start spitting on someone no matter how much they sense evil.
They do not necessarily know why it is so - did that person murder someone? Is he innately a person of greed, malicious? Is he a thief? When, where and how are not known. It is not noble in any manner or way to slander, however warning people is well in their rights.
