The Death Penalty; do all opinions have equal right of respect?

“In some countries people say that the death penalty is a deterrent and it works. No, it doesn’t work because the death penalty is an act of violence and there is always the possibility of errors” Alex Mayer MEP

Are all opinions to be respected equally? It is a long held liberal and democratic principle that all opinions have equal right of repect. Countries that believe in the efficacy of the death penalty, such as Thailand, should be free to retain the death penalty, execute those condemned to death, and have the right to do so.

Now, it happens that the Council of Europe, with a membership of countries from the Atlantic Coast to the Pacific, imposes abolition of the death penalty on its member states, 47 in all, thus creating the largest group of abolitionist states in the world. What if a retentionist country approaches the Council of Europe for funding in a truly deserving cause, let us say for famine relief, or basic educational development? Can the Council of Europe impose as a condition of funding, complience with abolition of the death penalty to which it obligates all its own member states? Recalling the historical fact that the current poverty of African and South American countries is due to colonial exploitation and current prosperity of Council of Europe countries, does the latter have the moral right to impose human rights options on the former. In a world where advance in human rights valuation is slowly leading to advance in abolition over retentionist countries, the debate over values is likely to assume the form of might over right when a triumphant majority is faced with a recalcitrant minority who cling for whatever reason to a retentionist stance.
