Well, it depends on "bad". The bible is very clear that sex acts between the same sex are wrong- however, as Romans 3:23 says, all have sinned and fall short of the glory of God. It is upon God to cast judgment, not us. As James 2:10 says "For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it." And not just in the bible, but looking at the natural order of the world, genders are designed to function in a certain way. But as we know, Jesus has washed all sins clean, so no matter the struggles people face with sexuality and gender identity, as Psalm 136:26 says, Give thanks to the God of heaven, for his steadfast love endures forever. By this we know God loves even the sinners, even the ones with sinful lusts and desires that go against nature, are loved and forgiven by God. Jesus' death on the cross paid for all sins, so no matter what sins people struggle with, they are forgiven through Christ.

In Hebrews 6 God shows that falling away from the righteous ways is not good, however, in Romans 8 the bible says For I am convinced that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, nor powers, nor height, nor depth, nor any other created thing, shall be able to separate us from the love of God, which is in Christ Jesus our Lord. To say for sure if someone can be unsaved is known only to God, however, the bible is clear that a Christian who is lukewarm and inactive is in the worst place of faith; Revelation 3:16 says So, because you are lukewarm, and neither hot nor cold, I will spit you out of my mouth. This speaks of sin, someone cold is far from God, someone hot is close to God, doing his works, spending time in prayer, etc. someone lukewarm is in the middle, not close to God but not a complete sinner. This suggests that someone can be unsaved, or perhaps, rather, not saved in the first place. The most important thing is to have faith. As said in 2

Corinthians 5:7 For we walk by faith, not by sight.

The Bible says, in Colossians 3:8 But now you must put them all away: anger, wrath, malice, slander, and obscene talk from your mouth. This shows that swearing and cursing are not of good, but evil; they stem from anger and wrath. James 3:10 says From the same mouth come blessing and cursing. My brothers, these things ought not to be so. This shows that in order to be received as someone who loves God and people, as servants of God and the people, we should avoid cursing and swearing as they make us seem like hypocrites, and can lead people away from the church and Gospel. This being said, Jesus forgives all sins, and while we should act in according to these scriptures, all sins are forgiven, this includes cursing and swearing.

The bible is fairly clear on war, seeing as God orders the Israelites to go to war several times. (in 1 Samuel 15:3, Joshua 4:13) Although the Bible says in Exodus 20:13 "you shall not kill", when the original Hebrew is taken into account the meaning is clear; the word kill in this context is more similar to the word murder, it is representative of premeditated, intentional, malicious killing, not war, which, in a world full of sin, is sometimes necessary.
