Intoxication is generally not considered a valid excuse for criminal behavior, as it is assumed that individuals are responsible for their actions, even if they are under the influence of alcohol or drugs.

The imminence requirement in self-defense means that the danger must be immediate and unavoidable, leaving no reasonable alternative but to use force in order to protect oneself.

The necessity defense allows individuals to engage in otherwise criminal conduct in order to prevent a greater harm or evil. In the given example, stealing food to feed a starving family may be justified as a necessary measure to prevent starvation.

The insanity defense is based on the idea that individuals who are mentally ill or disordered may not be able to understand the wrongfulness of their actions and, therefore, should not be held criminally responsible.

Under the duress doctrine, threats of imminent death or serious bodily harm, threats to harm a loved one, and threats to expose embarrassing information may be valid defenses, as they can create a reasonable fear that compels an individual to commit a crime. However, threats to destroy property generally do not qualify as a valid duress defense.

The purpose of the entrapment defense is to prevent law enforcement from using unfair or deceptive tactics to induce individuals to commit crimes that they would not otherwise have committed.

An affirmative defense is a defense in which the defendant admits to committing the crime but argues that they are not criminally responsible due to certain circumstances. Self-defense is a classic example of an affirmative defense.

Excuses negate the defendant's criminal intent by showing that they did not have the necessary mental state to commit the crime, while justifications negate the wrongfulness of the defendant's actions by showing that they were justified in committing the crime.

Defense of property is generally not recognized as a valid excuse for homicide, as the value of human life is considered to outweigh the value of property.

The immediacy requirement in the duress defense means that the threat of harm must be immediate and unavoidable, leaving no reasonable alternative but to commit the crime in order to protect oneself or others.

The mistake of fact defense allows individuals to avoid criminal liability if they mistakenly believe that certain facts exist that would make their conduct lawful. In the given example, if a person mistakenly believes that the person they killed was a burglar, they may be able to avoid criminal liability for homicide.

The insanity defense is not based on the defendant's lack of criminal intent. Instead, it is based on the idea that individuals who are mentally ill or disordered may not be able to understand the wrongfulness of their actions and, therefore, should not be held criminally responsible.

Under the necessity defense, preventing imminent death or serious bodily harm, preventing the commission of a crime, and preventing the destruction of property may be valid defenses. However, preventing the disclosure of embarrassing information generally does not qualify as a valid necessity defense.

The purpose of the duress defense is to protect individuals who are forced to commit crimes against their will by threats of imminent death or serious bodily harm.

Self-defense is not a recognized excuse for theft, as it is only applicable in cases where an individual is using force to protect themselves or others from imminent harm.
