Comprehensive answers are in my previous posts ...
Basic summaries:
1. Of course our Heavenly Father cares about all His children. However if they choose wickedness and abominations instead of following His commandments then consequences will follow... that is Eternal Law.
2. This life is a trial. Free agency, and consequent incorrect choices leads to a world of wars and suffering. When we pass from this mortal world we will be judged on how we dealt with the trials of mortality.
3. Our Spirit leaves our mortal body and depending on our worthiness, passes on to the next stage of our eternal life .
4. Of course.
5. Pray to your Heavenly Father, in genuine sincere faith and belief, in the name of Jesus Christ, repenting of all sin and committing to obey Eternal Laws, the Commandments, and the true Gospel of Jesus Christ. Listen to the promptings of the Holy Spirit.
6. Read the Scriptures and follow the true Gospel of Jesus Christ.
