"Never attribute to malice that which can be adequately explained by stupidity."

"So furiously each other did assayle,
As if their soules they would attonce haue rent
Out of their brests, that streames of bloud did rayle
Adowne, as if their springes of life were spent;
That all the ground with purple bloud was sprent,
And all their armours staynd with bloudie gore,
Yet scarcely once to breath would they relent,
So mortall was their malice and so sore,
Become of fayned friendship which they vow'd afore."
— Edmund Spenser (The Faerie Queene, Books Three and Four)

— Charles Dickens (Oliver Twist)
