Repentance For Sins Done In A Pre-planned Manner
Both your questions have been answered by God in the Quran. God is not obliged to do what people think. People need to know His justice: لَّيْسَ بِأَمَانِيِّكُمْ وَلَا أَمَانِيِّ أَهْلِ الْكِتَابِ ۗ مَن يَعْمَلْ سُوءًا يُجْزَ بِهِ وَلَا يَجِدْ لَهُ مِن دُونِ اللَّهِ وَلِيًّا وَلَا نَصِيرًا [It should remain clear to you that success in the Hereafter] is neither dependent on your desires nor on those of the People of the Book. [Certainly not!] In fact, he who does evil will be punished for it, and will find none against God to be his protector and helper. And he who does a virtue, whether man or woman and also has faith, then such are the people who will enter the Paradise of God and they will not suffer the slightest injustice. (4:123) The criteria of Taubah for those who commit a sin in the flow of emotions and those who stick to it deliberately: إِنَّمَا التَّوْبَةُ عَلَى اللَّهِ لِلَّذِينَ يَعْمَلُونَ السُّوءَ بِجَهَالَةٍ ثُمَّ يَتُوبُونَ مِن قَرِيبٍ فَأُولَٰئِكَ يَتُوبُ اللَّهُ عَلَيْهِمْ ۗ وَكَانَ اللَّهُ عَلِيمًا حَكِيمًا ‎ ‏ وَلَيْسَتِ التَّوْبَةُ لِلَّذِينَ يَعْمَلُونَ السَّيِّئَاتِ حَتَّىٰ إِذَا حَضَرَ أَحَدَهُمُ الْمَوْتُ قَالَ إِنِّي تُبْتُ الْآنَ وَلَا الَّذِينَ يَمُوتُونَ وَهُمْ كُفَّارٌ ۚ أُولَٰئِكَ أَعْتَدْنَا لَهُمْ عَذَابًا أَلِيمًا [It should, however, remain clear that] God’s responsibility to forgive is only for those who commit a sin while being overwhelmed with emotions and then repent soon. So, it is they to whom God shows His mercy and accepts their repentance and God is All-Knowing and Wise. On the contrary, there is no repentance for those who sin all their lives and, when the time of death approaches for any of them, he says: “Now I do repent!” Similarly, there is no repentance for those also who die as disbelievers. It is these for whom We have prepared a grievous punishment. (4: 17-18)
There can be many cases, where emotions and planning can intermingle, they have to be seen from case to case, that is why God has not mentioned them, just told the two broad categories. what falls in between them will be judged by God on merit, with justice and mercy.
