Hindsight
They say hindsight is twenty-twenty. Arachne is one of the few people who can claim to know that from experience.
In hindsight, she realized that she should have turned Cronus over to the gods instead of striking a bargain with him. If she had, she could have saved herself a lot of trouble.
She wouldn't have had to spend time capturing the various heroes or deal with the consequences of their eventual escape. She was just fortunate that Atlanta had interceded on her behalf with the gods. Otherwise, she might have spent the rest of her life as a spider.
