No one deserves a second chance, but God loves us so much He gave us one anyway. Anyone can get into Heaven, they just have to believe in Him during their time on Earth. During Jesus' crucifixion, he was put between two thieves who probably murdered a lot of people, but moments before his death, one of the thieves recognized that He was Jesus and they shouldn't be mocking Him, and right then and there Jesus told that thief that He'll see him in Heaven. And in case you think that's made up, my dad's grandpa wasn't a Christian, but on his death bed my dad gave him the gospel, and as he left he could feel the Spirit itself say "Don't worry, I have him now." That isn't something someone could just make up. So, yeah, nobody deserves a second chance because we're all sinners (you, me, our families, everyone) but if we put our trust in Jesus, it doesn't matter who you are, He will make you whole again.
