Problem is you are using a few quotes from the bible that say what you want. And ignoring the ones that contradict it. Or trying to minimize it by saying it only applies to killing and torturing people. When in reality that exception doesn't exist:
Matthew 19
Just then a man came up to Jesus and asked, "Teacher, what good thing must I do to get eternal life?"
"Why do you ask me about what is good?" Jesus replied. "There is only One who is good. If you want to enter life, keep the commandments."
"Which ones?" he inquired. Jesus replied, "'You shall not murder, you shall not commit adultery, you shall not steal, you shall not give false testimony, honor your father and mother,' and 'love your neighbor as yourself.'"
Loving your neighbor isn't more or less than the others. All those count. If you aren't a christian for breaking one according to you it's the same for the others. And the love of life you talk about comes from love of money too for example as jesus says later:
23 Then Jesus said to his disciples, "Truly I tell you, it is hard for someone who is rich to enter the kingdom of heaven.
24 Again I tell you, it is easier for a camel to go through the eye of a needle than for someone who is rich to enter the kingdom of God."
So rich people aren't christian either right? And everyone that doesn't sell their possessions to follow jesus.
You miss the point. The point isn't the idea of "keeping" the commandments once or twice or three times. The point is to keep them without fail all the time.
Lots of people never murder, even once in their life. Lots of people never commit adultery, even once in their life. Then it starts getting difficult.
Most people steal something now and again, even if it is only something little. Most people say something false about somebody else once in a while. Most people dishonor their parents once in a while, even if it is very slight. And nobody loves all his neighbors all the time.
Since everybody fails in some of these things, there is nobody who will be saved for eternal life, right?
Ah, but there is Somebody who kept all these commandments perfectly. It is Jesus. Then Jesus took all the punishment that God would have dealt out to all the people for all the wrong things that they had done. Jesus took it when He died on the cross. Then He arose from death, because He didn't even do anything wrong in His dying to deserve death.
Now, Jesus offers eternal life to all who believe in Him. Why do they have to believe in Him? Because God is entirely truthful. And the only way for you, a sinner, to obey the commandments perfectly is to obey them through Jesus, by believing in Him and His offer of eternal life.
Does this make sense to us? Somewhat, but not entirely. We simply don't think along these lines deeply enough to understand it easily. The thing that we CAN understand and do, is to believe in Jesus for salvation.
When the people asked Jesus what they needed to do to do the works of God, Jesus answered that the work of God was this... to believe on the One that God sent... namely Himself.
