I mean good life in relation to others, like helping the weak, giving to charity etc, not in relation to your inner spiritual life.
Okay, I'm going to continue to answer from the Christian viewpoint. So far, we've been dealing with a fairly simple perspective: the image is of being right/wrong in relation to God, and thus being forgiven/not forgiven.
However, in Christianity, being forgiven is not all that happens to you. When you come to God and ask him for forgiveness, God forgives you but also changes who you are. In fact, you begin to become like Christ himself - so we are forgiven, but also on the inside we are different. We begin to take on the character and behaviour of God himself.
So to answer your question at face value: there is nothing stopping you. One of the only people who we knew was right with God was a terrible criminal, hanging on a cross alongside Jesus - he didn't even the luxury of a death bed. But he asked God for forgiveness and trusted in God's grace rather than in his own goodness (the lack of which was pretty obvious at that point), and so he was right with God.
What reason is there for living a 'good life'? Well, I'll give you a more concrete example than that hypothetical situation. Take me. I asked exactly the same question you did - why bother, if I'm already 'going to Heaven'? But the point in what I was saying earlier was that, if I was indeed forgiven by God and in relationship with him, then on the inside I'm a different person.
So you see, it's not so much a question of "I have to do this to go to Heaven", but more like "Hey, I'm different now - how can I live the way I used to?". To give a crude illustration, if I was a fish who had just evolved into a land creature, why would I go back to swim in the ocean? I'm new now, so I ought to live in a new way that's appropriate for me.
Therefore, the reason that
I help the weak and give to charity is not because I need to do that to be saved, but because this is my new identity now - the Bible says that when God forgives people, his aim is to "purify for himself a people that are his very own, eager to do what is good".
