Most people who go to hell are not evil. Most people are not evil, but they are idiots. Everyone here knows a lot of people. Of these, how many are really bad? The minority. So, that’s why Christ says that the road that leads to hell is wide. You see, if the path that leads to hell were only for the wicked, it would be narrow. But the path of perdition is not only for the wicked, it is for the wicked and the foolish. What does Christ say at the end of the Sermon on the Mount? He says that whoever hears his words and puts them into practice is likened to a wise, prudent man. And whoever hears his words and does not put them into practice is not compared to an evil man, but to a fool who has wasted his whole life.
Quoting Frithjof Schuon:
''Many people imagine that Hell is for those who killed, stole, fornicated, lied and so on, and that it is enough to have abstained from these actions to deserve Heaven; in reality, the soul goes to the fire for not having loved God or for not having loved him sufficiently; this can be understood by remembering the Supreme Law of the Bible: to love God with all our faculties and all our being. The absence of that love is not necessarily murder or lying or any other transgression, but it is necessarily indifference; and this is usually the most widespread vice, it is the very mark of the Fall. It is possible that the indifferent are not criminals, but it is impossible that they are saints. They are the ones who enter through the ‘wide gate’ and walk through the ‘spacious way’, and it is of them that the Apocalypse says: 'So, because you are lukewarm and neither cold nor hot, I will spew you out of my mouth" .
Indifference to the truth and to God is next to pride and is not without hypocrisy; its apparent sweetness is full of sufficiency and arrogance; In this state of mind, the individual is content with himself, even if he accuses himself of small faults and is modest, which does not compromise him in anything and, on the contrary, reinforces his illusion of being virtuous. It is the criterion of indifference that makes it possible to surprise the ‘average man’ as in ‘flagrante delicto’; to take the most hidden and insidious vice, so to speak, by the throat and prove to each one his poverty and misery; it is this indifference which is, in short, ‘original sin’ or which manifests it most fully’’.
