Morphology

aider = aid (transparent) = aid + er

Agentive formation from 'aid' using the productive suffix '-er'; the criminal context is pragmatic rather than morphological.

Etymology

Aider comes from an old French word and the Latin root adiutare, both meaning 'to help'. So, an aider is someone who gives help, and it can also mean a person who helps another to commit a crime.
