several people will tell you different things, some will say that God created humans and told all angels to love them above all others, even God himself. lucifer refused to do so, and fell from grace. others will say that it was because he was prideful and wanted to have a throne above God's throne, thus he fell. this is also probably not correct. there is only one mention of 'lucifer' in scripture,Isaiah 14:12 and actually lucifer means, lightbringer, morningstar, or the shining one, this term can be used the refer to all angels as they are God's shining ones, this is why often when referring to Satan, people use the name lucifer to describe the angel he was before he fell. this being said, it also has been cited that 'lucifer' was a cherubim, these are creatures that support God's throne, that is not to say that they are lowly angels, but actually are granted the power by God to touch his throne, meaning they are very high ranking angels of a sort. speaking specifically of scripture, lucifer himself is not mentioned, but there are several accounts of kings that are corrupt, the famous one being of Babylon, that are cast downward. the word Satan means opponent, adversary, or accuser. in the Hebrew tradition, this refers to the angel that is the heavenly prosecutor who brings a persons sins against them for judgment. job 1:6. in dealing with the idea of the king of Babylon, he basically exiled all Jews to Babylon, this is talked about in Job, and actually could be the whole basis of the good vs evil thought. before this, God was the creator of good and bad, beautiful and repugnant. it is only after the exile of the Jews (as job was not finalized until after the exile) that we see this sift of there being a different entity for evil. in the Old Testament we see several instances of God being quick to anger and to punish, which are said to be evils. in the New Testament, Christ died for our sins, thus giving us the ability to be forgiven for our sins. this idea leads people to believe that God is all forgiving and is only synonymous with good. this seems to not be true as God is only forgiving of those who repent of their sins, suggesting that God is still capable of causing evil. sin in humans seems to not be an outside force that tempts us, but a result of the human condition we call free will that was giving to us from God. there are still several approaches to look at, but these seem to be the most supported with other writings from the time of The Bible, as well as by scholars that i have been reading about. i am still looking into this idea as i have a very important paper to do on this topic, and the best thing i can recommend is to look at scripture. find a version of the bible that is easily understood by you, look up online verses that mention Satan or lucifer or anything like that and derive a meaning for yourself. there is no reason to take another persons word for it (which is the worst thing you can do as it leads to cults and ignorance) when you can derive your own answer, and take from scripture what it means to you.
i hope this helped, i know that it is not a direct answer, but its the best i can do. and if you are looking at this from a religious point of view, remember that the bible was written by man. it is fallible, and the only real answer of any substance you can get is to pray and talk to God for your answer, any answer humans can give you may not be correct as there is no way to prove that it is.
