In what way can illegal activities be viewed as harmful or destructive consumer behaviours?

Illegal activities-Many consumer behaviours are not only self-destructive or socially damaging, they are illegal as well. Examples include theft, shoplifting, employee pilferage, serial wardrobing, arson, and insurance fraud. Losses account for a substantial increase in the cost of goods since these losses are passed on to the consumer.
Anticonsumption-Products and services are deliberately defaced or mutilated, such as product tampering (e.g., Tylenol), graffiti on buildings or subways, and so on. Causes may range from peer pressure to rage against some aspect of society. The destruction of property by vandalism both contributes to additional costs to the consumer and threatens society by potentially denying access to necessary services like public transportation and communication.
