Kant thought a human being has a predisposition to preserve himself in his nature and called the contrary of this "killing oneself". And depending on the extent conducted he classified it into either total "suicide", or only partial mutilating oneself. Which form of killing oneself it may be, if it is an act of willfully killing oneself, he asserts it ultimately an evil deed(peccatum) and a crime, whatever the reason of that may be. For killing oneself is an act contrary to the obligation of universal natural law of self-preservation and a making use of a human being himself as merely as a mean to an end, which is an act prejudicial to the dignity of a human being as a person having a worth in itself and hence the act contrary to the moral law that use humanity in his own person always as an end. Interestingly, Kant does not see the problem of suicide as a problem that can be solved at the level of individual practical reason. A human being is not only weak in the temptation of feeling, but he also has a propensity to act contrary to the moral commands even when they admit the authority of the moral law, that is, he has a radical innate evil and hence personal efforts alone are not enough against the moral evils such as suicide. So Kant suggests that the finite rational beings establish an ethical community, solely designed for the preservation of morality by counteracting the radical evil with united forces. And in distinction from countries under the positive laws he calls that community "a universal republic based on laws of virtue", which means an invisible community united under laws of virtue. Kant clearly pointed out that the social malady of suicide is not a problem that can be solved at the individual level, but just needs the help of the whole community. This indication of Kant is still persuasive today with his philosophical insights into the causes of suicide.
