Seven deadly sins

The Catholic Church has just announced that there are a new seven deadly sins. They are

• Bioethical" violations such as birth control.
• "Morally dubious" experiments such as stem cell research.
• Drug abuse.
• Polluting the environment.
• Aggravating social injustice by contributing to the widening gap between rich and poor.
• Excessive wealth.
  

This is in addition to the old list

• Lust.
• Gluttony.
• Greed.
• Envy.
• Wrath.
• Pride.
• Sloth, which replaced sadness in the 17th century.

I am some what surprised at this list and that they have come out with a new list. Pleasantly surprised that Catholic Church sees the destruction of the world, social injustice and excessive wealth as major problems that need to be addressed. I was sadly surprised that certain things were not on the list. Things like abortion, terrorism and sexual abuse.
Over all I am not sure that making a list of the worst sins is the best idea. First of all, it comes across as really judgmental. This list would be a lot more powerful if sexual abuse was included because the Catholic Church would have been identifying some of their sins. Second reason a list might not be a good idea is that this implies that Christianity about following rules and not about following God. Third, I have real doubts that this list is going to change anything.
