Matthew 13:36-43
Jesus dismissed the crowds and went into the house.
His disciples approached him and said,
"Explain to us the parable of the weeds in the field."
He said in reply, "He who sows good seed is the Son of Man,
the field is the world, the good seed the children of the Kingdom.
The weeds are the children of the Evil One,
and the enemy who sows them is the Devil.
The harvest is the end of the age, and the harvesters are angels.
Just as weeds are collected and burned up with fire,
so will it be at the end of the age.
The Son of Man will send his angels,
and they will collect out of his Kingdom
all who cause others to sin and all evildoers.
They will throw them into the fiery furnace,
where there will be wailing and grinding of teeth.
Then the righteous will shine like the sun
in the Kingdom of their Father.
Whoever has ears ought to hear."

"All who cause others to sin and all evildoers will be thrown into the fiery furnace."
What does it mean to cause others to sin? The Church calls this "scandal", and it is an important enough teaching to have several paragraphs of the Catechism devoted to it. Here they are:
Respect for the souls of others: scandal
2284 Scandal is an attitude or behavior which leads another to do evil. The person who gives scandal becomes his neighbor's tempter. He damages virtue and integrity; he may even draw his brother into spiritual death. Scandal is a grave offense if by deed or omission another is deliberately led into a grave offense.
2285 Scandal takes on a particular gravity by reason of the authority of those who cause it or the weakness of those who are scandalized. It prompted our Lord to utter this curse: "Whoever causes one of these little ones who believe in me to sin, it would be better for him to have a great millstone fastened round his neck and to be drowned in the depth of the sea."
Scandal is grave when given by those who by nature or office are obliged to teach and educate others. Jesus reproaches the scribes and Pharisees on this account: he likens them to wolves in sheep's clothing.
2286 Scandal can be provoked by laws or institutions, by fashion or opinion.
Therefore, they are guilty of scandal who establish laws or social structures leading to the decline of morals and the corruption of religious practice, or to "social conditions that, intentionally or not, make Christian conduct and obedience to the Commandments difficult and practically impossible."This is also true of business leaders who make rules encouraging fraud, teachers who provoke their children to anger or manipulators of public opinion who turn it away from moral values.
2287 Anyone who uses the power at his disposal in such a way that it leads others to do wrong becomes guilty of scandal and responsible for the evil that he has directly or indirectly encouraged. "Temptations to sin are sure to come; but woe to him by whom they come!"
