Since I am a Christian I believe that God created the original body of a human. And His hand is involved in the creation of every human since then. So being disrespectful to a human's body is to be disrespectful to one of God’s creations, and therefore disrespectful to God. I realize when a person is deceased it’s because the soul has left the body of that person and the body is only a carcass with no thoughts or brain activity when it is without a soul. The fact remains that the body was created by God and that is why we have to have respect for how it’s disposed of when someone is deceased. Regardless of who it is, anyone of any religion (or cult even) or the most sickening or the most treacherous person in the world they are still a human being.
The other night I spent about an hour reading the comments about what France should have done to the bodies of the radical Muslims that were killed while committing terrorist criminal activities recently in France. Some of those comments were just as bad as the terrorism that was committed by those radicals. What some commenters recommended as to how the dead Muslims' bodies should have been treated are just has bad as what those Muslims did to bring on the ire of the people.
The things that some of those commenters suggest what should have been done to those bodies were really disgusting and insulting to one of God's creations. I don’t agree with most of these commenters. I must say, it’s not the body that is at fault but the brain of that person that was brainwashed at a young age into believing a radical ideology.
I don’t believe in the actions of those radicals, but what some people would like to have done with the bodies, I don’t agree with that. To show disrespect to a human body is to show disrespect to one of God's creations. To suggest that sort of thing is undignified and I would say not acceptable in God's eyes.
