My answers to the 2 questions are CAPITAL YES.
let's look into the scriptures.
As Jesus traveled through the cities and villages of Galilee performing miracles, a man who was possessed with a devil was brought to Him; the man was also blind and unable to speak. Jesus healed him, causing many to be amazed and wonder if He was the promised Messiah .
Bad spirits are same as demons, devil or Satanic Spirits.
Again let's look at Matthew 8:28-34 (NASB)
Jesus Casts Out Demons
28 When He came to the other side into the country of the Gadarenes, two men who were demon-possessed met Him as they were coming out of the tombs. They were so extremely violent that no one could pass by that way. 29 And they cried out, saying, “[a]What business do we have with each other, Son of God? Have You come here to torment us before [b]the time?” 30 Now there was a herd of many swine feeding at a distance from them. 31 The demons began to entreat Him, saying, “If You are going to cast us out, send us into the herd of swine.” 32 And He said to them, “Go!” And they came out and went into the swine, and the whole herd rushed down the steep bank into the sea and perished in the waters.
In conclusion, not only can bad Spirits (Demons) touch human being, they can also posses human beings.
However, for this cause, Jesus Christ was made manifest that he might destroy the works of bad spirits (Demons)
He is still doing it today. As Christ was yesterday, do he is today and so he gona be forever.
