Would you support your child if they undoubtly committed murder?

No.
I could not look another Mother in the face and honestly tell her that my child should be exempt from the consequences of their actions, because I know that if I was at the reverse end of the stick and it was my child that was murdered, I would want justice. I could not knowingly deprive another family of justice, even if it is my child.

If there is one thing that I want my children to be taught, if I could only choose one lesson that would go through to them in my 18 years of parenting, it is taking responsibility for your actions. Stepping up and saying "Yeah. It was me, I fucked up. I made the decision, I made the call. I made the wrong call.". I'd be very saddened and very tempted to try to help my child, but in the end, my support would be minimal. My child is no more important than the person that they killed.

Good thing I will never have this problem. It hate children.

I don't and would NEVER have children. I can't stand them.

Depends on their reason. If it was in self-defense, I'd still love them. But if it was cold stone killing, No I wouldn't support them. Disown them is a better word.

This question is impossible to answer, untill you're put in this situation.

The moral of this pole is dont have kids because they could grow up into a murderer.

It really depends. And honestly, killing someone is not always murder. If someone broke into my house with a weapon, I would shoot them and it would probably kill them. That is self defense, not murder. If I hit a pedestrian with my car and killed them (accidentally, of course) that is manslaughter. So, assuming the legal definition of murder, i.e. a planned, conscious attempt to kill someone, I think that I could not forgive the child, but I would want a fair judgment to be issued, so I might hire a lawyer but would probably just let my child keep the court-appointed one (if the evidence is overwhelming, they're going to get convicted anyways.)

I'd help my child commit the murder

it can be your child, brother, parent, wife or very close friend, you dont turn them in, you help them hide the body if needed.

I would always love and support my child. I would also remind them that they need to learn from this, so I wouldn't bail them out. If my kid killed someone, I would hire an attorney with the agreement that they would plead guilty.

I highly doubt I'll even have kids anyway, but in some case that these events did happen, no. I'm not going to protect someone who killed an innocent.

No I believe in justice. If I had a kid I would make sure he/she took responsibility. Then again, that's why I don't plan on ever having kids. Haha who knows who will be raising the next Ted Bundy..

If it were self-defense, I would support them, they would probably feel awful as well about the whole thing.

Cold blooded murder, no. I couldn't just let them get away with it and besides, despite the fact they killed someone, if I know about the crime, I'm an accomplice after the fact, or whatever the term is.

But mostly no because of morality.

it would depend on the reason why they thought it was necessary to end the persons life.

I wouldn't because my hypothetical child would either go to juvy for being young or jail where s/he wasn't even my responsibility in the first place.

Depends on why they did it.

I guess it really depends on why they did it..

If it was in self defense than yes. If it wasn't self defense but had a reason behind it than still yes but it would be a complicated thing that we'd have to talk about. If it was for no reason than no.
