Solitaires and Assassins

Once when society rejected them
They headed for the hills
Becoming solitaires
Living all alone

But have things changed
To where it is today
They're more likely to pick up a gun
To make someone groan?

They seek to etch their names
In the history books of time
They seek to take out
Someone who is well known

Lincoln had a killer
And he was way back then
But over all, it seems back then
More were solitaires
More of them just lived alone
