If nobody will hire me, should I turn to crime to pursue a career in programming? I ask because if there's no legal entry-level jobs due to the oversaturation, I might have to go underground for it.

Presumably, you have a 4 year CS degree, and not just some certificates from a certificate mill.

You took those performance reviews to heart, and aimed some of your school curriculum at addressing any areas where your performance was less than stellar, and kept notes, so now you have KPIs (Key Performance Indicators), both where you fell short in each internship,and a list of what you did to address your shortcomings
