Your thread poses many questions for clarification. Firstly, by brutality, I assume you mean death?
In answer to your corresponding question, there is a misconception about God. Whilst He is all-loving, in the sense that He loves all people with no discrimination, He is also righteous and with that, comes judgement.
Think about it for a minute. We are made in the image of God, so you will know this is true because you will experience something similar in your own heart. Whatever quality of goodness is in you will automatically be repelled by some of the worst evil you see around you in the modern day. Evil such as schoolgirls like the Chibok girls, being kidnapped and raped, one reportedly to the point of being able to only walk on all fours, or evil such as domestic violence, child neglect, paedophilia. God is just the same, except the only difference is that some things we normalise and accept are not normal or acceptable to God. That is the only difference. However we know what it is to have righteous anger stirred. It is the reason we seek justice and order. It is the reason we want these poor girls to be found and restored and repaired, and for the men who treated them so brutally to be brought to justice.
Which brings me to my second point. As humans made in the image of God we recognise there is a need for structured order; in other words, rules and laws. There is also a need for judgement when that law is broken. Again, God is just the same as us (or more accurately, we are the same as God!). When God's law is broken there needs to be a consequence. The book of Romans says "The wages of sin is death". That is our consequence. We now all die, which was not God's first plan for mankind, but was the consequence of breaking God's rules. However judgement and death is not the whole story, the verse in Romans goes on to say "the wages of sin is death but the free gift of God is eternal life"
You mention brutality and if you mean death, then we all die one day. Not everyone dies peacefully in their sleep in the middle of the night, some die painfully, slowly, or suddenly. What we all have in common is that we will all die! God appoints a day for us to be born and a day for each of us to die, only He can determine this. Since He is God, it's up to Him when those days will be, not up to you and me! God has not done any injustice whether we live one day or a decade. Just because we don't like it or would choose something different doesn't make God wrong and us right. In fact, every day we are alive is God's grace to us.
So, do I believe in an all-loving God when I see He is also a God of judgement? Yes of course I do.
