I thought you had a degree in psycholoy, Skybird? Those behaviours, depsite being truly repugnant, are easily explainable -not justificable- sadly. A bad youth education with "everything-is-allowed", a "no-frustration-allowed" society where tolerance is excessive and limits are hardly recognizable, and BINGO, you get young bastards who have no conscience of the feelings of other persons but are just filled with hate and at the same time "empty" in terms of personal wealth. Psychopats. That's the clinical name for them, the only difference is that in earlier centuries they were born like that, and now they are formed like that but our welfare states

Such is life.
