Concerning soteriological justice and those who have never heard the Gospel, my Bible says:
Romans 1:18-23 NASB
18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who suppress the truth [fn]in unrighteousness, 19 because that which is known about God is evident [fn]within them; for God made it evident to them. 20 For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse. 21 For even though they knew God, they did not [fn]honor Him as God or give thanks, but they became futile in their speculations, and their foolish heart was darkened. 22 Professing to be wise, they became fools, 23 and exchanged the glory of the incorruptible God for an image in the form of corruptible man and of birds and four-footed animals and [fn]crawling creatures.
[Some things about GOD are self-evident and those who reject the self-evident truths are condemned for their rejection not for their ignorance.]
Romans 2:12-16 NASB
12 For all who have sinned [fn]without the Law will also perish [fn]without the Law, and all who have sinned [fn]under the Law will be judged [fn]by the Law; 13 for it is not the hearers [fn]of the Law who are [fn]just before God, but the doers [fn]of the Law will be justified. 14 For when Gentiles who do not have [fn]the Law do [fn]instinctively the things of the Law, these, not having [fn]the Law, are a law to themselves, 15 in that they show the work of the Law written in their hearts, their conscience bearing witness and their thoughts alternately accusing or else defending them, 16 on the day when, according to my gospel, God will judge the secrets of men through Christ Jesus.
[The Law is instinctively written on the heart of all mankind. Those who do not have the Gospel are condemned or acquitted by their conscience as they "love God and their neighbor" or do not.]
Just a small reality check concerning the unsaved. For the Amazon natives, life was lived in fear of accidentally offending some spirit and being punished with a drought or a bad hunt or the sickness and death of a child. The Gospel freed them from that fear. For the unsaved in modern society, random chance (good and bad luck) and ultimate purposelessness is the 'demon' that terrorizes them. The Gospel is the only thing that can free them from that.
... but you feel free to leave them in a world of fear and powerlessness as your act of 'kindness'.
[The fact is "Enter through the narrow gate; for the gate is wide and the way is broad that leads to destruction, and there are many who enter through it. For the gate is small and the way is narrow that leads to life, and there are few who find it." ... most of the dead are in Hell. Hearing the Gospel only shines a light on the narrow gate.]
