My opinion is that TO FIND sounds similar to ONLY TO DO SOMETHING, which is usually used to say something disappointing,
eg She turned up the driveway, only to find her way blocked.
On the other hand, you should've asked why the tenses are not consistent, which is my question and I hope a native English speaker can tell:
What would a wife who comes home to find dirty dishes in the sink and her husband watching TV say?
Is it OK to use CAME?
