Hadith on Evil: The most hated people to Allah are criminals, corrupters, and killers

Ibn Abbas reported: The Prophet, peace be upon him, said, “The most hated of the people to Allah are three persons: a person who deviates into the unlawful, a person who seeks for the traditions of ignorance to
remain in Islam, and a person who seeks to shed another’s blood without right of justice.”

[Sahih Bukhari, Book 83, Number 21]

عَنْ ابْنِ عَبَّاسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ أَبْغَضُ النَّاسِ إِلَى اللَّهِ ثَلَاثَةٌ مُلْحِدٌ فِي الْحَرَمِ وَمُبْتَغٍ فِي الْإِسْلَامِ سُنَّةَ الْجَاهِلِيَّةِ وَمُطَّلِبُ دَمِ امْرِئٍ بِغَيْرِ حَقٍّ لِيُهَرِيقَ دَمَهُ

6488 صحيح البخاري كِتَاب الدِّيَاتِ بَاب مَنْ طَلَبَ دَمَ امْرِئٍ بِغَيْرِ حَقٍّ
