Does Judaism Give Second Chances?

There is always Teshuvah. Hashem's mercy and forgiveness is limitless. No matter how far you stray and sincerely ask Hashem to forgive you, Hashem will forgive.

Yechezkel- Ezekiel 18:21-23 And if the wicked man repent of all his sins that he has committed and keeps all My laws and executes justice and righteousness, he shall surely live, he shall not die. All his transgressions that he has committed shall not be remembered regarding him: through his righteousness that he has done he shall live. Do I desire the death of the wicked? Says the Lord God. Is it not rather in his repenting of his ways that he may live?

Hashem wants your sincere repentance.

Bereshit-Genesis 4:7 Is it not so that if you improve, it will be forgiven you? If you do not improve, however, at the entrance, sin is lying, and to you is its longing, but you can rule over it."
Here Hashem speaks to Cain saying that he can improve himself and Hashem will forgive him. Like a loving parent Hashem wants the best for you. Reply
