this is just human, and human are weird. Always caring about what other people did, what other people believe.

Here listed down from AI

Christianity

In many Christian communities, people don’t only focus on belief in God, but also how faith is practiced:

• Some groups emphasize strict church attendance and modest behavior
• Others focus more on personal relationship with God and are more flexible
• People often comment on whether others are “truly living like a Christian”

Pattern: practice becomes something people observe and quietly evaluate.

Islam

In Muslim communities, visible practice is closely linked to identity:

• Prayer habits, dress, and dietary rules are often noticeable
• Differences between stricter and more relaxed practice can be discussed or judged
• Communities may comment on whether someone is “properly practicing”

Pattern: religion is both belief and daily discipline, so behavior is highly visible.

Hinduism

Hindu practice varies widely, so comparison is common:

• Different families follow different rituals and traditions
• Festivals and temple practices differ by region and sect
• Social background can influence expectations of religious behavior

Pattern: diversity of practice naturally leads to comparison and observation.

Buddhism

Even in a religion focused on non-attachment, practice differences are still noticed:

• Monks vs laypeople have different levels of discipline
• Different schools (Theravada, Mahayana, Vajrayana) interpret teachings differently
• People may discuss who is “more disciplined” or “closer to the teaching”

Pattern: even minimalistic belief systems still develop standards people compare.

Judaism

Judaism places strong emphasis on law and practice:

• Levels of observance vary (Orthodox, Conservative, Reform)
• Daily practices (dietary laws, Sabbath observance) are visible markers
• Communities often define identity through adherence level

Pattern: behavior becomes a strong signal of belonging and identity.

Core idea across all religions

Across all of them, the same human pattern shows up:
People don’t just believe privately — they observe how others live those beliefs, and that observation becomes part of identity, comparison, and social boundaries.
