A person can get killed for marrying into the wrong caste and it happens often enough in India. https://indianexpress.com/article/cities/pune/dalit-youth-be...
A low caste person can get killed if they "trespass" even by having mustache which is only allowed for the upper caste in parts of India or if they are seen eating before the so-called upper castes. Or for just making eye contact!

Or you can get killed for something as simple as riding a horse! https://thewire.in/caste/family-alleges-dalit-boy-was-killed...
Or being seated in front of the upper caste.. https://www.hindustantimes.com/india-news/dalit-youth-thrash...
In almost all of these cases the cops and the law enforcement will put pressure on the victim's family to withdraw cases.
Any Indian who argues that caste oppression doesn't happen in India now is not misinformed - they are just lying.
