Lot's wife disobeyed God, and I remember thinking that I'd probably do the exact same thing of looking back out of curiosity if I were in that position. When God gives an order, He means it, like when He told people not to touch the Ark...and look what happened to the guy that did.
As for Lot's daughters, what I was told was that the angels were holy and having them be defiled by the people was far worse than his daughters. Not that it was anything I could do; giving someone my daughter!!
They were men wanting to have sex with men. They turned down the girls and kept going after the guests. For another example, Look at Judges 19:
16 And, behold, there came an old man from his work out of the field at even, which was also of mount Ephraim; and he sojourned in Gibeah: but the men of the place were Benjamites.
17 And when he had lifted up his eyes, he saw a wayfaring man in the street of the city: and the old man said, Whither goest thou? and whence comest thou?
18 And he said unto him, We are passing from Bethlehemjudah toward the side of mount Ephraim; from thence am I: and I went to Bethlehemjudah, but I am now going to the house of the Lord; and there is no man that receiveth me to house.
19 Yet there is both straw and provender for our asses; and there is bread and wine also for me, and for thy handmaid, and for the young man which is with thy servants: there is no want of any thing.
20 And the old man said, Peace be with thee; howsoever let all thy wants lie upon me; only lodge not in the street.
21 So he brought him into his house, and gave provender unto the asses: and they washed their feet, and did eat and drink.
22 Now as they were making their hearts merry, behold, the men of the city, certain sons of Belial, beset the house round about, and beat at the door, and spake to the master of the house, the old man, saying, Bring forth the man that came into thine house, that we may know him.
23 And the man, the master of the house, went out unto them, and said unto them, Nay, my brethren, nay, I pray you, do not so wickedly; seeing that this man is come into mine house, do not this folly.
24 Behold, here is my daughter a maiden, and his concubine; them I will bring out now, and humble ye them, and do with them what seemeth good unto you: but unto this man do not so vile a thing.
25 But the men would not hearken to him: so the man took his concubine, and brought her forth unto them; and they knew her, and abused her all the night until the morning: and when the day began to spring, they let her go.
26 Then came the woman in the dawning of the day, and fell down at the door of the man's house where her lord was, till it was light.
27 And her lord rose up in the morning, and opened the doors of the house, and went out to go his way: and, behold, the woman his concubine was fallen down at the door of the house, and her hands were upon the threshold.
28 And he said unto her, Up, and let us be going. But none answered. Then the man took her up upon an ass, and the man rose up, and gat him unto his place.
29 And when he was come into his house, he took a knife, and laid hold on his concubine, and divided her, together with her bones, into twelve pieces, and sent her into all the coasts of Israel.
No angels in this story to blind the evil doers.
