Hello truthseeker1
In Mattew he repents, but repenting alone will not get you into the Kingdom of God.
Reoent and be baptized in the Spirit, Judas may have realised he was wrong but afterward killed himself. If you or anyone calls upon God to be saved and repents and kills themself will not get into the Kingdom of God.
As it is written: James 4:17 - Therefore to him that knoweth to do good, and doeth it not, to him it is sin.
I look forward to hearing from you soon!
Take care!
