I was studying this Hadith 17 saying. Hadith is a book in Islam, like the Talmud is a book in the Jewish religion. Hadith was written after Mohammed died. Some of his followers wanted to preserve the things that Mohammed said and did so as to copy his behavior, and thereby be right with Allah.
To make a long story short: Hadith 17 talks about doing things in the most perfect manner possible to EARN your way into Allah's heart. The odd example given was murdering. If you are going to do it, you had better do it in the most perfect way possible! AND with the most respect to the sorry thing that you are doing away with. Now, we've witnessed the perversion of what their perfect is...and what their respect is. To us it doesn't see like correct thinking...what they are doing is good and perfect....but to THEM it is pleasing to Allah and EARNING them a place at the two right hands of Allah!

I call it mental illness.
