Satan
Each sect of Judaism has its own interpretation of Satan's identity. Conservative Judaism generally rejects the Talmudic interpretation of Satan as a metaphor for the "yetzer hara", and regard him as a literal agent of God. Orthodox Judaism, on the other hand, outwardly embraces Talmudic teachings on Satan, and involves Satan in religious life far more inclusively than other sects. Satan is mentioned explicitly in some daily prayers, including during Shacharit and certain post-meal benedictions, as described in Talmud and the Jewish Code of Law. In Reform Judaism, Satan is generally seen in his Talmudic role as a metaphor for the "yetzer hara" and the symbolic representation of innate human qualities such as selfishness.
Haskalah
The spreading of Haskalah affected Judaism as a religion because of how much the different sects desired to be integrated, and in turn, integrate their religious traditions. The effects of the Enlightenment were already present in Jewish religious music and opinion on traditionalism versus modernization. Groups of Reform Jews such as the Society of the Friends of Reform and the Association for the Reform of Judaism were formed because they wanted and actively advocated for a change in Jewish tradition, mainly rituals like circumcision. 
Another non-Orthodox group was the Conservative Jews, who emphasized the importance of traditions but viewed with a historical perspective. The Orthodox Jews were actively against these reformers because they viewed changing Jewish tradition was an insult to God and that fulfillment in life could be found in serving God and keeping his commandments. The effect of Haskalah was that it gave a voice to plurality of views, while the orthodoxy stubbornly preserved the tradition, even to the point of insisting on dividing between sects.
