there is a conscious sinner, he is a sinner that know he is sinning and he continues sinning because he believes that in the future he will stop sinning after he get what he wants and he somehow will be forgiven by god .
Well this is the weird duality of the Christian faith - we are all sinners yet saints. This mindset you present though is clearly destructive and evil. Sinning to get "what we want" is objectively bad, because what pleases God should please us. Given the nature of us as fallen descendants of Adam, we rebel liberally and do not and can not inherently, nor perfectly, desire the will of God. The future doesn't exist - there is no guarantee of anything in the next hour, and to top it off, there is no path by sinning that leads to less, for even one sin leads to damnation. Active, honest repentance, confession, and absolution, (ideally to a ordained minister of a traditional, catholic church, but any faithful catholic will work as in both situations it is God's grace not ours) in the name of the slain and risen lamb, the perfect son of God Jesus Christ, is the best option.
In the end, it is not outside of God's perfect love and compassion to forgive this stretch of sin, but God, knowing all the contents of our heart, knows our intentions and true feelings. There is never a justification for sin, and if you were to die in this actively misuse of God's grace, you only risk your salvation. Don't think you can run one past the Lord, the first will truly be the last. Do not be of the world, only in it - the beatitudes point to how blessed detachment from the world is - never want to sin, ever.
and there is a unconscious sinner, he is a sinner that has good intentions, but he doesn't know that he is sinning.
You have reasonably described all Christians in this case - it is impossible for Christians to numerate all the sins in which we have offended God, and it is impossible to fully grasp his Will. There is no pure works path to righteousness, as all sin unconsciously given that we cannot fully know the extents of our true sin. This is why faith/grace are mandatory.
In the case of the unconscious sinner where they are catechized, this points to a lack of proper catechesis, which was a big issue during the reformation, and remains a big issue to this day (topic for another post, not this one). Catechesis is really a lifelong journey, not something that occurs at Confirmation and ends after. All christians should NEVER stop striving to know God's will and directions, and the intent to learn what is right and wrong in order to stop sinning is just. The grace of god extends bountifully to all who invoke the name of the trinity, and any good prayer or confession should state that we confess all things that we have knowingly or unknowingly done or left undone. Confessing in this way ensures that the forgiveness is granted and we have life everlasting.
In the case of a person who could not or did not hear the word (think jungle people, aborted fetuses, babies, the unwell), there is no clear answer. The best thing we can do is pray for God's mercy on them. God is merciful and just - he slaughtered his own innocent Son for our fallen race out of nothing more than compassion and love - whatever happens to them is perfect and just.
In the case of the person "who has good intentions" but rejects the Holy Trinity as God, this person cannot be saved. All have sinned and fall short of the kingdom of God, and only the things described above can truly lead to salvation. Any non-christian can do "christian things", but they are all in vain as salvation is by grace FIRST (and in some schools of thought, grace alone
). There is no greater sin that the rejection of He who gave you life.
