Evil Men

Some men it seems are evil; they are lacking any sense
Of what it's to be human; they see terrible events
As preferable to others which bring joy to all around;
Their view of good and evil will quite frequently be found
To be completely opposite to the views of normal souls,
With hurting and not caring being the focus of their goals.
They like to boast they're brutal, and enjoy the life they lead;
Depravity to them is just a normal human need.
They can't conceive within their heads how other people feel,
Their hearts though beating normally are often hard a steel.
Why are some men like that?  It's really hard to tell,
And it's not the sort of subject on which people like to dwell.
