What will happen if an untouchable touched a brahmin on purpose?

In traditional Hindu society, if an "untouchable" (now referred to as Dalit) were to touch a Brahmin on purpose, it could lead to severe social repercussions. Brahmins, considered the highest caste, might feel that their ritual purity has been compromised, potentially resulting in social ostracism or rituals of purification. Historically, such an act could provoke strong reactions from the community, reflecting the deep-rooted caste tensions and discrimination in Indian society. However, contemporary views are shifting, with growing movements advocating for equality and social justice.
