Truthfulness is God's sword on earth and in every soul. But most people don't take, it's too strong of a nature and weapon, and so they lie/deceives to others and themselves.
So is God going to condemn all these liars? Yes and no. Michael and the Angels under him will try to use their niceness or charity or good acts in general out of kindness and compassion, even in their deceiving to themselves state, and defeat their darkness.
Truthfulness is a stage if one get's, they can slice and dice through the shadows and get to God's light easily and remain there.
If someone fears God, they will attain wisdom, whether they know God exists or not. But in the mean time, till they do, Michael uses their good deeds.
The problem is when someone is shameless, their good deeds are done with same intention of their evil deeds, and then Michael and his Angels can't really help such a person. This is the state of people who fornicate in public (porn stars) for example, none of their actions can Michael actually help them with and his Angels can't help such souls, but will be overcome by the darkness if they try.
According to hadiths of Imam Musa Al-Kadhim (A) - the long and certain one that he talks about reasoning and intelligence of believers, he describes 72 armies of intelligence and 72 armies of ignorance.
Adan (call to prayer) summons the armies of light and Aqama makes them stand strong. Salah connects them to God in various ways when one is not intoxicated with love of Dunya and Iblis deceptive call.
So if one is not truthful, it doesn't mean God close the door of salvation for them, through other deeds they can attain salvation and eventually become truthful. But if someone let's the armies of ignorance make them disbelieve in God and his Messengers and chosen ones and scriptures and Angels, then everything falls apart. If the light is destroyed by our living sins, then God tries his best, but usually there is nothing he can do. What I mean by best, is within reasonable paradigm. Of course, if God wanted to, he can make sure we all get guided and every soul receives it's guidance. I'm not talking from that perspective, but from the reasonable paradigm and design of God of the trial.
To answer your question though, I believe the door of all good is Mohammad (s). Mohammad is my one word. If you connect to him and ask him to intercede for you, ask him along with his family, wonders open up, and we eventually leave our lying to ourselves and others state, to that of the light of God including his ultimate sword which is a state of being fully truthful.
Allah (swt) opens up so many doors when people come to the family of the reminder of their time and ask them for intercession and ask them to ask forgiveness for them for their evil deeds, and seek their needs from God through them.
As for one word for evil, it's ungratefulness.
And peace be upon who follows the guidance, it's been revealed to me that punishment is upon who denies and turns away.
