I don't believe in anything specific, so my religion says: "do whatever you want."
Half joking, half serious.
I come from a Catholic country, so suicide is considered unnatural.
However, it is a bit complicated.
The church system usually criticizes suicide and treats it as an act of cowardice and immorality.
But Christianity, or simply Catholicism, is not just a church.
Some things can be interpreted in different ways.
People who commit suicide do not necessarily go to hell.
It all depends on the circumstances.
In the past, people who committed suicide were not buried in Holy Land after death in a normal cemetery.
This has changed.
The rhetoric of religion is changing.
It is less restrictive in some respects.
Different commandments/words/parables/etc can be interpreted in different ways.
If someone is a Christian/Catholic, I believe that they should not trust the church system completely.
Of course, I'm not a believer, so I don't care.
