The amount spent on him during his imprisonment was 2.5 Million Dollar.

One amount spent on one side is an amount received on the other side. It's a cynical system, one might say; depends on how you see it. A prisoner is indirectly the work giver of many peoples. Those who administer the prison, those who work there as security staff, those who clean there, those who deliver food, those who bring clothes, the electricity company, tech tech company, the fence company, the street builders and even the politicians, and so on and so forth. Citizens are also an indirect beneficiary from prisoners. The after prison procedure again, give work for peoples in the social sector and so on. Police force "needs" crimes in order to be justified as protectors or preventers from criminal acts. Judges and courts live from crimes coming on trial. It's all a huge inter-woven complex.

You could say that the prisoners pay indirectly back for what crime they have been convicted. And so they are worth more alive than dead.

Do you actually have the death penalty in your country?

The greater interest of society is not unified, and it's actually not bad in total that it is not unified in all questions. Conflict is always a chance to debate and debate is being in touch, and being in touch is to find answers to questions. Or to be earnest and honest about the things that cannot be changed, for example.
