over the period of years people faiths become refined to the point that all that have faith only do good?
The problem with that expectation is that most religions are based on exclusivity, being special, being separate, being better, being sanctified.
The Christian scriptures clearly state that those that do not know God and those who do not obey the good news about Jesus Christ will suffer the punishment of eternal destruction.
The purpose of the Jewish Torah is to set the Jew apart, sanctify, as holy in the midst of the unholy, the non-believers.
Perhaps someone can attest to the accuracy of the following quotes from the Qur'an...
Believers, take neither Jews nor Christians for your friends. They are friends with one another. Whoever of you, seeks their friendship shall become one of their number. Allah does not guide the wrong doers. (Quran: Al Ma'idah: 5 - 51)
Believers, do not seek the friendship of the infidels and those who were given the Book before you, who have made your religion a jest and a pasttime. (Quran: Al Ma'idah: 5 - 57)
Fight those who believe not in Allah nor the Last day, nor hold the forbidden which hath been forbidden by Allah and his messenger, nor acknowledge the Religion of Truth from among the People of the Book, until they pay the Jaziyah with willing submission. And feel themselves subdued. (Quran: Al Taubah: 9 - 29)
