Wizards and  racists.  They may have realized/expected that most 
students with Dark tendencies would end up in Slytherin.  By 
allowing the House to continue they insured such students would be 
easy to spot and observe.

This theory sounds interesting and plausible to me, but I sincerely 
hope that it will some kind of mix between four others you named , 
but not this one. 
It would mean more than certain coldbloodeness on the Founders part. 
 It would mean that for ages ahead they decided to gave up on all 
kids , who MAY become racists pureblood theorists. It would mean 
that after the age of eleven such kids don't deserve to be saved. 
And I really really don't want that to be the case.
Slytherin House is the house of racists now, IMO, but I hope that we 
will see that it does not consists ONLY of racists at the end of the 
books.
