The Buddha shares the six roots of disputes - 1) anger and resentment, 2) denigration and contention, 3) envy and miserliness, 4) deceit and hypocrisy, 5) evil desires and wrong view, 6) clinging to views, holding on to them, and insisting on them - that lead to one not fulfilling the training, to dispute in the community, and to the harm and suffering of many.

Vivādamūla sutta - Root Of Disputes

"Bhikkhus, there are these six roots of disputes. What six?

1 Here, bhikkhus, a bhikkhu is angry and resentful. When a bhikkhu is angry and resentful, he dwells without respect and deference toward the Teacher, the Dhamma, and the Saṅgha, and he does not fulfill the training. Such a bhikkhu creates a dispute in the Saṅgha that leads to the harm of many people, to the unhappiness of many people, to the ruin, harm, and suffering of gods and humans. If, bhikkhus, you see such a root of dispute within yourselves or in others, you should practice to ensure that this harmful root of dispute does not arise in the future. In this way, there is the abandoning of this harmful root of dispute. In this way, there is non-arising of this harmful root of dispute in the future.

2 Furthermore, bhikkhus, a bhikkhu is a denigrator and contentious. When a bhikkhu is a denigrator and contentious, he dwells without respect and deference toward the Teacher, the Dhamma, and the Saṅgha, and he does not fulfill the training. Such a bhikkhu creates a dispute in the Saṅgha that leads to the harm of many people, to the unhappiness of many people, to the ruin, harm, and suffering of gods and humans. If, bhikkhus, you see such a root of dispute within yourselves or in others, you should practice to ensure that this harmful root of dispute does not arise in the future. In this way, there is the abandoning of this harmful root of dispute. In this way, there is non-arising of this harmful root of dispute in the future.

3 Furthermore, bhikkhus, a bhikkhu is envious and miserly. When a bhikkhu is envious and miserly, he dwells without respect and deference toward the Teacher, the Dhamma, and the Saṅgha, and he does not fulfill the training. Such a bhikkhu creates a dispute in the Saṅgha that leads to the harm of many people, to the unhappiness of many people, to the ruin, harm, and suffering of gods and humans. If, bhikkhus, you see such a root of dispute within yourselves or in others, you should practice to ensure that this harmful root of dispute does not arise in the future. In this way, there is the abandoning of this harmful root of dispute. In this way, there is non-arising of this harmful root of dispute in the future.

4 Furthermore, bhikkhus, a bhikkhu is deceitful and hypocritical. When a bhikkhu is deceitful and hypocritical, he dwells without respect and deference toward the Teacher, the Dhamma, and the Saṅgha, and he does not fulfill the training. Such a bhikkhu creates a dispute in the Saṅgha that leads to the harm of many people, to the unhappiness of many people, to the ruin, harm, and suffering of gods and humans. If, bhikkhus, you see such a root of dispute within yourselves or in others, you should practice to ensure that this harmful root of dispute does not arise in the future. In this way, there is the abandoning of this harmful root of dispute. In this way, there is non-arising of this harmful root of dispute in the future.

5 Furthermore, bhikkhus, a bhikkhu has evil desires and holds wrong view. When a bhikkhu has evil desires and holds wrong view, he dwells without respect and deference toward the Teacher, the Dhamma, and the Saṅgha, and he does not fulfill the training. Such a bhikkhu creates a dispute in the Saṅgha that leads to the harm of many people, to the unhappiness of many people, to the ruin, harm, and suffering of gods and humans. If, bhikkhus, you see such a root of dispute within yourselves or in others, you should practice to ensure that this harmful root of dispute does not arise in the future. In this way, there is the abandoning of this harmful root of dispute. In this way, there is non-arising of this harmful root of dispute in the future.

6 Furthermore, bhikkhus, a bhikkhu is clinging to his own views, holding on tightly, and giving up with difficulty. When a bhikkhu is clinging to his own views, holding on tightly, and giving up with difficulty, he dwells without respect and deference toward the Teacher, the Dhamma, and the Saṅgha, and he does not fulfill the training. Such a bhikkhu creates a dispute in the Saṅgha that leads to the harm of many people, to the unhappiness of many people, to the ruin, harm, and suffering of gods and humans. If, bhikkhus, you see such a root of dispute within yourselves or in others, you should practice to ensure that this harmful root of dispute does not arise in the future. In this way, there is the abandoning of this harmful root of dispute. In this way, there is non-arising of this harmful root of dispute in the future.

These, bhikkhus, are the six roots of disputes."
