See, a friend of mine owned some of those bonds (Icelandic in that case, but similar). He saved money to support his family in case where they'd need it. The money evaporated when Icelandic banks defaulted. The money that was used to prop up Greece came from people that worked for it - some directly, some indirectly. Why should their money be taken from them? Why should German social services be slashed because the EU still needs to funnel more money into Greece? [1] I totally agree that Greece needs help, but I don't have a good answer for those that need to pay for it.

[1] we had a major slashing of social services with the Hartz4-laws. Things are certainly not as ugly as in Greece, but Germany has the highest percentage of low-wage labor in Europe. Germany as a country is rich, but a lot of Germans pay the price.
