Is taking offense a sin?

Then He said to the disciples, "It is impossible that no offenses should come, but woe to him through whom they do come! It would be better for him if a millstone were hung around his neck, and he were thrown into the sea, than that he should offend one of these little ones. Take heed to yourselves. If your brother sins against you, rebuke him; and if he repents, forgive him. And if he sins against you seven times in a day, and seven times in a day returns to you, saying, 'I repent,' you shall forgive him." (Emphasis added)

Jesus entered the temple courts and drove out all who were buying and selling there. He overturned the tables of the money changers and the benches of those selling doves. ""It is written," he said to them, 'My house will be called a house of prayer,' but you are making it 'a den of robbers.'" The blind and the lame came to him at the temple, and he healed them."

"If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother. But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of two or three witnesses. If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector." Matthew 18:15-17

There are six things that the Lord hates, seven that are an abomination to him: haughty eyes, a lying tongue, and hands that shed innocent blood, a heart that devises wicked plans, feet that make haste to run to evil, a false witness who breathes out lies, and one who sows discord among brothers.
