Final answer:
Hacking into a computer system and distributing MP3 files over a peer-to-peer network share a moral similarity in terms of violating intellectual property rights, but they differ in intent.
Step-by-step explanation:
A moral similarity between hacking into a computer system and distributing MP3 files over a peer-to-peer network is the violation of intellectual property rights. Both actions involve unauthorized access to or use of copyrighted material, which harms the creators' economic rights and undermines their ability to profit from their work.
A moral difference between the two actions is the intended purpose. Hacking into a computer system is typically done with malicious intent, seeking personal gain or causing damage, while distributing MP3 files over a peer-to-peer network may be driven by individuals' desire to share and access content without directly profiting.
