Personally - I think we could safely argue that in general - the invaders, whoever they are and whenever it is ---
are the bad guys
if there is a bad or good
it's an invader who comes in to take what someone else has - it's really that simple
an invader invades because their own territory has been overused - they have used too much of their own resources and require to go and pinch someone elses
it's as simple as that
there is of course - the possibility of displaced persons - displaced by some invader - which means that they have to flee - and, sometimes, become invaders themselves
but, even then - it takes a bad guy invader for that chain of events to happen
one group who exceeds the resource in their own space
whether it's 'bad' or not - well, depends on your philosophy ---------- it's called survival and evolution
