"Knowledge Will Give You Power, But Character Respect."
Getting being Branded as some nasty creature of the society is a lifetime pain for anyone along with the family! It is really impossible to hide individual character flaws.
Anybody may become successful changing his name from 'Miah' to 'Chowdhury' over the night through affidavit ; but no such systems of doing 'Character Affidavit' has been invented yet.

Society always follow the natural course that is it rejects all bad ones & welcome good ones.
