Just a ''musing'', food for thought ramble (my usual :biggrin: )
We discuss BG's all the time - mindsets, psyche etc - but one major element which strikes me as helping define bad guys is - pure and simple - lack of scruples.
''I want'' = ''I will obtain by any means". The how and where will be down to what is convenient - with little thought for any potential victims.
These folks have probably never stood back to think - "I wonder if I would like that done to me?"
My scruples are linked inextricably with my conscience - my guide thru life - my repository for values and what I regard as right and wrong. Admittedly, (thanks to my late and dear departed parents - much credit goes to them for my own values), we have once more a potential background of unscrupulousness regarding BG's (and budding BG's) which may be linked to family inadequacies. That said - I do not permit those aspects to excuse bad behavior or condone criminal actions. Right and wrong should be pretty darned obvious come supposed 'adulthood'.
The final part of this is - lack of scruples - viz unscrupulousness - can readily make for cold, hard headed evil intent by the criminal. Remember this - because in situations where the victim for example ''appeals'' to a rapist to ''be kind and let me go'' - ''please don't shoot me'' - it needs remembered that the perpetrator has no scuples and so possibly no qualms about what he does. Consequences matter little.
In a defensive situation - if we are to come out breathing - we'd best bear this in mind. Once the unscrupulous criminal is bent on achieving his ends - nothing very often will be allowed to stand in the way - be it person or any obstacle. If we are under threat - respond - it may be a life-saver.
