Here are following suggestions for you:
* don't copy paste - no matter you are giving credit or not
* for AdSense your blog must be 6+ months old and should have ample advertising space + original content
* by registering a .in domain you have restricted your website to rank well only on google.co.in. I am not saying your website is not going to rank well in other Google TLDs, but you have to work more harder (super duper unique and quality content) in order to rank well
* create a privacy policy page for your site before applying for AdSense
This may even lead to jail, if the original blogger finds out the misuse.
The laws of many nations may be different, but we should not go against any of them. This is what I wanted to say.
Sorry, you are wrong
