Behaviour and not Family defines the Outcaste:
Once a brahmin asked the Blessed Buddha: What makes an Outcaste?
The Blessed One
explained: Not birth or family, but evil bad
Whoever is angry, irritable, cruel, hypocritical, has wrong views, and who
false, pretending, and deceitful, such one should be known as an outcaste.
Whoever in this world harms living beings, who has no pity, who terrorizes,
besieges villages and towns as a notorious dictatorial oppressor,
such evil one should
be known as an outcaste.
Whoever in a village or a forest takes by theft, what was not given to him,
lend money, when requested denies to repay, who due to desire
for some trifle commits
violence, or adultery, such one should be known as an outcaste!
