What are various kinds of terrorism including state sponsored terrorism & their causes ? What are remedies ? ?

First define terrorism in generalised form clearly having no flaw, error, eccentricity, drawback & loopholes in the definition. What are root causes of them ? Are dishonesty & injustice responsible for the same ? Are ingeneities in human societies too responsible to some extent at all ? Do denial, discrimination & deprivation play any role at all ? What are the aims of terrorism ? Why are people ready to sacrifice their lives so easily, never seen before even a decade earlier ? Please answer in balanced manner & not one sided. Narrow minded, communal, fascists & extremists keep away. No abusive & similar languages please. How to end permanently with minimum loss ?
