No one has complete ownership of his body but the use only, since man is God's steward, so to speak; if he abuses or destroys his own body he inflicts an injury on God, but he does not inflict an injury (strictly so-called) on himself since injury is always concerned with the rights of others.
275 First Principle. The direct killing of oneself on one's own authority is a most grievous sin against divine, Natural, and ecclesiastical law.
I do not know what you mean by "eternal sin", but what I do know is that, suicide is indeed a sin.
Catholics view sin as an act that God finds offensive. Catholics believe there are two types of sin, venial and mortal. Whereas a mortal sin takes a person out of God's graces, a venial sin does not. Catholics believe that all sins can be forgiven by God; no sin is too big for God to forgive.
Roman Catholics believe in the concept of purgatory, a place where souls are purified before entering heaven. They also believe in the doctrine of original sin, which states that all humans inherit sin from Adam and Eve. On the other hand, Orthodox Christians do not believe in purgatory and have a different understanding of original sin, viewing it more as a tendency towards sin rather than an inherited guilt.
Catholics believe that suicide is a mortal sin. However, if the person who committed suicide did so without full knowledge or without complete consent, then it is possible that they can get to heaven. Catholics can not know if these things are happening, so they pray for those who have taken their own lives.
