Why did the Emperor in Dune want the Atreides family to be massacred?

In the Dune novel by Frank Herbert, the Emperor Shaddam IV sees Duke Leto Atreides as a potential threat to his power due to Leto's growing popularity and the loyalty of many Great Houses to him. 

The Emperor fears that Leto may be able to gather enough support to challenge his rule, leading him to see the Atreides family as a threat that must be eliminated.

To get rid of the Atreides, the Emperor devises a plan to lure them into a trap. He offers them control of the valuable spice production on the planet Arrakis, also known as Dune, which he knows is coveted by the Harkonnen family, long-time enemies of the Atreides.

The Emperor hopes that by pitting the Atreides against the Harkonnens, they will destroy each other and the Emperor can then swoop in and take control of Arrakis.

This plan involves some subterfuge, as the Emperor pretends to be benevolent and even arranges for his trusted advisor, Count Fenring, to offer Duke Leto a chance to become the Emperor's right-hand man. This is intended to lull Leto into a false sense of security and make him more willing to accept the offer of Arrakis.

Once the Atreides family arrives on planet Arrakis, the Emperor's plan comes to fruition. 

The Harkonnens launch a surprise attack on the Atreides, with the help of the Emperor's Sardaukar troops. The attack is swift and brutal, and most of the Atreides are killed or captured. Duke Leto is taken prisoner and eventually killed by Baron Harkonnen himself.

As for why the Emperor did not destroy the Atreides homeworld, Caladan, it is likely because he knew it would be too risky. The Atreides were a powerful and respected family, and destroying their home would have been seen as a major act of aggression. This could have led to a full-blown war between the Emperor and the other Great Houses, which would have been costly and dangerous for everyone involved. 

By eliminating the Atreides on Arrakis, the Emperor hoped to remove the threat to his power while avoiding a direct conflict with the other Great Houses.

In conclusion, the Emperor saw the Atreides as a threat to his power and devised a plan to eliminate them by luring them into a trap on Arrakis. The plan involved using the Harkonnens as pawns and the Emperor's own troops to defeat the Atreides. However, the Emperor did not want to risk further conflict by attacking the Atreides' homeworld, Caladan, which is why he chose to eliminate them on Arrakis instead.
