1- Yes I understand your concerns. We are witnessing very difficult times. However, it’s still possible to raise good children. It all depends on how committed parents are to giving their children a good spiritual upbringing. If from day one parents are alert and give their children a good foundation, then chances are the children will grow up to be good.
2- Parents don’t own their children. Allah owns us. As parents we do our best to give our children a good upbringing, but ultimately Allah is the one who guides them. Ask Allah to guide them everyday and leave the rest on Him.
3- Islam recommends us to get married and have children, even in difficult environments. So by starting a family you are following the Sunna of the Prophet (s). You will be doing what your Creator has recommended to you.

4- If in the future things get very bad in your country you can migrate to a country with a better environment. Remember Islam was based on migration—so sometimes migrating to a better place will protect your family. Always be open to that.
So as long as you know your Islamic priorities, you will make your children your priority in your life, you have a plan to give them a good moral and religious foundation and you are willing to migrate one day if you have to, then go for it and ask Allah to bless you. Don’t deny yourself the opportunity of having a family. Ask Allah to make your children the supporters of Imam Mahdi (a).
