Most sentient beings are accustomed to creating unwholesome karma.

Many people diligently study the Dharma teachings every day, and one could say they are conscientious and devoted, yet occasionally, when encountering remarks that slander the Three Jewels—the Buddha, the Dharma, and the Saṅgha—they give a word of praise. That single "like" destroys most of the merit and virtue accumulated in their practice, so that no matter how diligent they are, their progress remains slight. Ignorance can severely obstruct the cultivation of the Path. If one does not find a way to repent of one's own ignorance, then in the end, whether one's wholesome karma outweighs one's unwholesome karma is hard to say. Why do so many people not realize that their own ignorance is so heavy? Why do they not realize that they lack wisdom, yet insist on voicing their ignorant, unwise opinions on the crucial parts of the Buddha's teachings? What will be the final outcome of such practice—why does no one stop to think about it? What is meant by unwholesome karma? Slandering the Three Jewels is the worst evil among evils—is there anything more evil than that? It would be better to commit the unwholesome deed of killing, for the retribution would still be smaller.  

Creating unwholesome karma is very easy—a single sentence can complete an unwholesome deed, even a single word can complete a great unwholesome deed, and even an emoji or a symbol can produce unwholesome karma. Few people would feel that there is anything improper about this, or that it carries any evil consequences. When the evil retribution arrives, they will not even connect it to the cause, never reflecting on or analyzing the source of the evil results, much less repenting of the unwholesome bodily, verbal, and mental actions they have committed. Many people do not even know which bodily, verbal, and mental actions are wholesome and which are unwholesome. Generally, they simply follow along with the ignorance and afflictions in their own minds, never going against their own unwholesome mental factors, letting their afflictive habits be revealed and spread freely. Most people have very poor awareness; they are oblivious to their own mental activities, lack the power of introspection (pratyavekṣā-bala), and do not wish to introspect—they merely comply and cover up for themselves. What is the result of such compliance? The result is that everyone has afflictions and suffering, everyone has obstructions, nothing goes as they wish, and at death they will fall into the three evil destinies to undergo immense suffering. Even after emerging from the three evil destinies, they remain unawakened, so that the vicious cycle continues endlessly, and the wheel of rebirth in the six destinies never stops.  

Creating wholesome karma is actually also very easy—a single sentence can complete a wholesome deed, even a single word can complete a wholesome deed, and even an emoji or a symbol can complete a wholesome deed. Yet many people disdain to do such wholesome deeds, because they lack such a habit. Every day, their unwholesome mental factors manifest more and more than their wholesome mental factors, and so everyone's unwholesome karma is greater and more abundant than their wholesome karma. This is why, although many people have faith in the Buddha and study Buddhism, they still fall into the three evil destinies at death and cannot secure a human rebirth—the proportion who go to the three evil destinies is over ninety percent, or even more.
