When it comes to who can be held legally responsible for a crime, it's important to understand that individuals who commit crimes are typically the ones held accountable. This means if someone does something against the law, like stealing or hurting someone, they can be considered criminally liable. It's a way for society to ensure people follow rules and behave in a way that doesn't harm others. However, there are also situations where someone might be held responsible even if they didn't directly commit the crime, like if they helped plan it or encouraged someone else to do it. Understanding who is criminally liable helps maintain fairness and justice in a community, ensuring that those who break the law face consequences for their actions. 

Penalties are consequences you face when you break rules or laws. They're like punishments. When you do something wrong, like breaking a rule in a game or driving too fast, there's usually a penalty. Penalties are important because they help keep things fair and safe. They encourage people to follow rules and behave well. Without penalties, people might do whatever they want without thinking about how it affects others. So, penalties serve as a kind of reminder to stay on the right track. They're a way to make sure everyone plays by the same rules and that there are consequences for breaking them.
