If I say something unwise or obviously wrong, either intentionally or unintentionally, people who heard it , follow my words and do wrong, I think, I should be accountable for it ! I sinned ! Back to Jesus, he said something like "if you do not love me more than youe parents, you can not be my disciple". Some zealous christians, who faced objection from parents, unwaveringly broke relationship with their parents for the sake of Jesus, this harms the feeling of their parents! Isn't that sin of Jesus for teaching people something like that?
