When you accept Jesus into your heart you become Christian. What do you mean by "true Christian"? Do you mean... did he always live rightously? No, not always. But who does. Just because you are Christian doesn't mean you are perfect and never do wrong again. But the more you get to know God and his word you fall in love with him(that's in my case) and you turn from alot of your old ways out of your love for him.We all are sinners and that was the whole reason Jesus came to die on the cross so we can be forgiven for the times when we do fall short and sin. But yes he did accept Jesus into his heart before he passed away.
