I am Christian and noticed some things you wrote which I will address now!
I dont think you should "Christians (or any other religion) can be the can be some of the biggest hypocrites (i think you meant to say how they can biggest hypocrites, not biggest hypocrite of the church but you can correct me if Im wrong)." Most religion teach morals of some kind and tell people to be moral and good. Not to hate, judge, be dishonest, and a hypocrite. Being a hypocrite is more closely related to that person's humanity than to their religious identity or in some cases faith, I'm sure. People who have great faith strive to live a godly life so they will do everything in their power to not hurt, harm, judge others. At least in Christianity.
Yes a lot of people in this world have a huge misconception of what sin is, especially in Christianity. In Christianity, the only sin that will and can send you to hell is not believing that God came manifested as a human (the human manifestation of God is Jesus Christ) and died so that he can pay for the price of sin (sin that was committed past, committed in the present, and will be committed) once and for all because he loves humans and want to save them. If you believe this, he promised eternal life with him in return. In addition, once you believe this, you also have to believe he beat death (rose again 3 days after being crucified) and is alive, will come back.
The seven deadly sins and all other human vices are things meant for the own good of the believer. If the believer does not obey and strive to stop such actions, it just means you wont get any or get few rewards when you finally stand before God and that God will call you to him faster (die faster [may not always be the case]or suffer more in life). When you do commit a vice then you bring dishonor instead of glory to him. However none of these are the reason why you will got to hell and all of these can be forgiven by Him if you ask for it and repent (acknowledge and promise to stop doing it [you start by doing less of it and eventually the holy spirit will lead you to never do it again])

In Christianity, first and above all, church is a place that connects/leads people to God. Preachers and pastors bring people to God and let them know that He exists. church is the place where all believers that acknowledge they are sinners gather to worship God and be grateful for dying for our sins, promising us a eternal life with Him in exchange. This is a place to learn about God, teach about God, support others to live a godly life together, and accept God as well. To Christians, judging is never permitted. It is not their place to ever judge anyone, only God's. They also know to never judge because they were sinful once before knowing and dedicating their lives to God. It is a grave violation and disgrace to judge others or say things that are not in the Bible. Just to let you know, Bible does not state that being gay will make you go to Hell when you die. That is why true Christians study and read the Bible every day vigorously because God commands not to add anything extra to the Bible or take out (delete) anything in the Bible. By saying and judging gays will go to hell, that person is lying and adding things to the Bible that was not there and was never written.
Yes love and grace is the biggest & best part of being Christian!! Of everything God commands, his greatest commandment is to love everyone, even strangers + enemies+ those who hate you and/or not good to you. Because God loved us to the point that He died for us (who are sinners), we must love others/pass on His love. God states thats how everyone in the world will know we follow him, believe him, love him, know him, and are his people a.k.a. Chrisitans "Christ ["Christ followers, forgiven ones"]!
