If you kill a family of five in cold blood as a non-Christian, but come to believe in Jesus Christ as your LORD and Savior, then you can ask God to forgive your sins, and you will be forgiven. You will not go to Hell.
This should answer your question.
But it is important to recognize that not all killing is sin. A US Soldier killing a Muslim ISIS soldier is not sin. In fact, it is the US Soldier’s duty to kill Muslim ISIS in a war between USA and ISIS.
The 10 Commandments forbids murder (unjust killing), but the Bible clearly shows that God allows killing, such as for soldiers. Sometimes, God commands killing. Read through the Book of Joshua and the Book of Judges in the Holy Bible.
For instance, opposing homosexuality and gay marriage is illegal in the United States of America. If you are a true Christian and oppose homosexuality, then you can go to prison after being arrested by the police. United Sates of America has chosen to stand against God and the Bible on the issue of homosexuality, unfortunately.
But it is important for Christians to always remember that while you keep God’s law, you may end up breaking your nation’s law. You have to be cunning enough to evade law enforcement, when you are serving Christ and honoring Christ with your body and skill sets.
And the Gospels of the New Testament emphasize that Jews tried to kill Jesus Christ throughout His ministry. And the New Testament emphasizes that it was the Jews who killed Jesus Christ. This Gospel Truth is emphasized again in the Book of Acts.

It is important for America’s Christians to boycott Starbucks to send a message to the Jewish billionaires and millionaires who want to use their money to destroy the celebration of Baby Jesus’s birthday.
Make anti-Starbucks shirts, hats, and billboards. Bash Starbucks on social media. Write complaints and negative reviews of Starbucks coffee on consumer reviews. Picket local Starbucks in your neighborhood. Picket the house of CEO of Starbucks. Mr. Howard Schultz, who is JEWISH. Flood Starbucks with protest letters. Show Baby Jesus that you love Him!
Unfortunately, the Republican Party is a party of failure.
It has failed to de-fund Planned Parenthood and stop using your hard-earned tax dollars to pay for abortions and other anti-Christian feminist activities of the Planned Parenthood – such as encouraging promiscuity among teenage women in America, like your daughters or granddaughters.
The Republican Party has failed to illegalize abortions.
The Republican Party has failed to illeagalize homosexuality and gay marriage.
Can you really trust a party that keeps failing to do what is right in the sight of the LORD?
We the people have the right to fold the current government and start a new one. Legitimacy of US government comes from the American people, and the American people have the right to change the entirety of the government and start a new one.
