Perhaps it is their own religious ideology and the rhetoric of their religious teachers that motivates terrorists?
Perhaps.
Difficult to pin it down on one thing.
Could it be . . .
Mental illness?
Extreme poverty?
A sense of excitement?
Military occupation by a foreign country?
Revenge?
Whatever the deciding factors are, terrorism is more likely in places of extreme wealth inequality, political instability, military occupation and economic sanctions - or at least some combination of these factors that leads one to choose a life of terrorism.
I’m making the distinction between a ‘guerrilla fighter’ and a ‘terrorist’ here – the emphasis of the terrorist being to target innocent and unarmed civilians going about their ordinary lives – including children?
Okay.
Why anything? But I don't believe it's my fault a person becomes a serial killer because the society in which I pay taxes allowed him to be born in poverty and sexually abused as a child. The judge will decide if it’s a mitigating factor, balanced against the ugliness of his crimes?
Some societies consistently have more serial killers than others, however. Others consistently have less. That tells me the environment matters. You can help shape that environment for better or worse.
The United States is a society that makes guns easily available. Since many of its citizens willingly want that type of environment despite having the highest number of serial killers in the world, then, yes, society is helping pull the trigger for its serial killers.
I'm not at all sure about this
Judging from the age of a lot of participants on this forum, they wouldn't have reached the age of 50 if they had been born in the 1800s (which had a life expectancy of 31). Child mortality has fallen off a cliff since then as well, so if you enjoy being around your children in the modern world, then you can be thankful you live in the 21st century.
You try going back to living on under 2 dollars per day then. In the 1800s most people lived in income level 1 in the image below. Show this to anybody that despairs about the world getting worse after citing rising inequality and rising inflation in recent decades. If the world is getting worse, tell such people that they should have simply lived in the 1800s then.
