My deepest sympathy to the people of spain and any Synthzoners in Spain. I hope they can find the killers who perpetrated this heinous act. I never agreed attacking anyone even if it is for revenge purpose (defending is another matter). These killers love to stir up things and do all these things to attract attention and revenge. When will people learn there is no end to these things ? You revenge by doing good to others, by being good to your enemies. Then they will hopefully change their mind/ways and realized their wicked heart. If you kill another person, then you will breed violence and revenge. Violence breeds violence. Revenge breeds revenge. I am not a pacifist but I learned this thru experience over the years.
