I find it heavily disturbing to blame engineers for something they had no part in deciding. If a politician/general/manager decides to use some technology for "evil" purposes (for whatever definition of evil), the responsibility should fall primarily on whoever makes that decision. Engineers who are unhappy with how their work is used are free to quit their jobs and work on something else (in most cases). However, since they get little say in how their work is used, they should also get little responsibility over it.
