You don't need to agree with me, but just be informed of the law. There are several scenarios where the felony murder rule applies and a huge factor is that there is no intent element to felony murder. In a scenario where someone is burglarizing your home (which is an inherently dangerous felony), and a bullet you fire at the burglar misses and kills someone, you are not criminally responsible.
See below:
Solo Actor: The felony murder rule is applicable in situations where a person commits a felony alone. The common example is arson. The defendant sets fire to a building with no intention of harming anyone, yet an unintended person dies in the fire (which could include firefighters).
Two or More Actors: Another common situation is an armed robbery where only one of the participants shoots the victim. In these cases, all of the participants in the robbery can be charged with felony murder, even though they didn't kill the victim nor were even present at the time the killing took place.
Victim or Bystander Killing: It's also possible that felony murder applies in cases where none of the felony participants killed anyone, such as when the victim or a third-party bystander kills someone while trying to stop the robbery. Felony murder in these cases would apply if a victim, a third-party, or even one of the felony perpetrators gets killed by someone other than a felony participant.
To clarify, this isn't something applied to the victim or good samaritan / bystander. It's applied to the surviving perp or perps.
