I guess this is not the last attempt of Catholic Church to discourage even further number of people to itself (read more on BBC News page):
The Vatican has brought up to date the traditional seven deadly sins by adding seven modern mortal sins it claims are becoming prevalent in what it calls an era of "unstoppable globalisation".
Those newly risking eternal punishment include drug pushers, the obscenely wealthy, and scientists who manipulate human genes. So "thou shalt not carry out morally dubious scientific experiments" or "thou shalt not pollute the earth" might one day be added to the Ten Commandments.
The Catechism of the Catholic Church states that "immediately after death the souls of those who die in a state of mortal sin descend into Hell".
