"On the other hand i.e. capital punishment is something that is simply not accepted in western Europe anymore."
It's time to change that.
That might be true in some special cases, but it is unlikely that it will happen in the next decades. Western Europe has completely different values in certain issues than i.e. the US or even your country. Maybe the cultural imprint plays a much bigger role than we all are thinking.
Besides - personally I share for sure a much more conservative view on punishment than most of my compatriots although I think that capital punishment should be restricted to really horrible crimes. For most murderers it is suitable enough to work for the rest of their lives in a quarry.
