Fired Employee Because Of Bad Attitude

There is no legal definition of "bad attitude". An employee can be dismissed only for misconducts which are specifically mentioned in the model standing order/ service rules of the company. "Hire and fire" policy is illegal.
Without knowing the nature of misconduct it is really not possible to give advice.
Even if you want to terminate him for a proper misconduct, there is a proper procedure --> issue charge sheet, give opportunity to explain, if not satisfied conduct domestic enquiry and then give punishment (terminate)
If you adopt hire and fire policy, the employee can easily ask for reinstatement and back wages before a labour court and win easily.

In my earlier posting I had stated, "What are the bad attitudes and how they are bad? The matter need not and should not judged in the larger context of the interest of the company and the societal values."
The second sentence may kindly be read as "The matter need not should not judged on the basis of one's predilections, but in the larger context of the interest of the company and societal values."
The error is regretted.

As stated by Riteshmaity, hire and fire policy is not legal. Being HR person, you may have to counsel the person to mend his attitudes. If it is still not working, then work-out your strategies to make him leave the job on his own, which will be safer.
