he answered your question in the video, where you listening?Oh free will okay.. So why does God create so many fukked up individuals then? You can still have free will and be a decent human being.
God doesn't create messed up people. he creates people with a choice to choose to be messed up.
For instance, you may be talking about people who are literally sociopaths. BUt guess what. their are many more sociopaths that never do anything harmful to others than their are crazy ones that do bad things to people. but you wouldn't know that because only thing you know is what the news tells you. you here bad things happening. and bam its a crazy fool aka a sociopath. so you automatically think all of these crazees are killers and do harmful things to people. not true.
Some do. Most don't.
You do realize MOST people don't do very extreme harmful things to other people. its actually a lot less people then you think doing really crazy things to others. but that's the news for you. that's what you remember, since everyday life doesn't deserve a special comment. so you think. its like not understand how special it is for you to wake up every morning. how many working parts that go into your heart beating as you type. to you that's erry day. But in reality you're a walking miracle. you're special. but its not news to you.
and again what did the man in the video say at the end. he gives you the ability to possibly see the worse kind of evil and also the ability to see the best kind of Love. without the ability to CHOOSE to do the right thing. you don't have the ability to CHOOSE to LOVE GOD. and with that ability or CHOICE. some people will choose to do the wrong thing. This is a product of that first sin.
The answer to "why do all bad things happen?" Is all due to the first sin. it broke man kind, but it also broke the world too. We are children of sin, while also being the seeds of what God created. We're both. and we struggle with being God's seeds over being seeds of a sinful nature. Some of us over come it more times than others. while some give up and don't trust God and stop loving God, then make a choice to harm others, or themselves.
