“Many people tend to focus on lobha and dosa as immoral. But moha is immoral too. The decision to carry out an act that one KNOWS will lead to suffering for oneself or others is immoral”. (Lal)
I do not belief this is true.
A lot of medical treatment, for example, comes with sufferings. The doctor or parents who know the treatment will come with pain and trouble do not act immoral.
A drug-adict knows that his detoxification will come with a lot of sufferings. But his decision is not immoral.
A Buddha discplines his discipels and teaches that his practise can come with much trouble and pain. He is not acting immoral and also not the practioners who feel a lot of pain and go to much trouble while practising.
