Lack of accountability
Poor control of finances
Domineering attitude
Assumes full control
Micro-manages
trusts no one other than him/her self.
and...
they think of themselves more highly than they ought.

Answer 2

If "charasmatic" is meant in the true definition, I take it as the 2nd.
1. Of, relating to, or characterized by charisma: "the warmth of a naturally charismatic leader" (Joyce Carol Oates).
2. Of, relating to, or being a type of Christianity that emphasizes personal religious experience and divinely inspired powers, as of healing, prophecy, and the gift of tongues.
Now, as far as a danger, in having ONE.... versus 2, 3 or more? I would hope that a charismatic leader would have a church full of charismatic people. One mind, One accord.
And then there would be teachers, youth leader etc, so there would be more, see.
Now if you are speaking of the "charismatic" part. By the definition I went to look up? I am one.
And so as that is my belief: Of, relating to, or being a type of Christianity that emphasizes personal religious experience and divinely inspired powers, as of healing, prophecy, and the gift of tongues.
I see no danger in it. I believe in the Book of Acts and the Day of Pentecost where the Spirit came down and the 120 did speak with the gift of tongues. Paul in all his writings in the New Testament was also one who did so, and I do not consider him a danger. He was the first to go to the Gentiles, all the others were to the Jews.
He was the writer of Romans, 1 and 2 Corinthians, Galatians, Ephesians, Philippians, Colossians, 1 and 2 Thessalonians, Titus, Philemon, Hebrews, Jude (I think).... leave these out and the New Testament would be very small indeed and our study to know would be much less. Paul a danger? No, I see him as an asset to the ministry.
The 12 disciples (Judas was replaced) who were with the 120 in the Upper Room all would be considered "charismatic", so remove the books of Matthew, Mark, Luke, John, Acts (Luke wrote that), the books of Peter, of John, Revelation.... in fact, now that I look at who wrote the Entire New Testament, "charismatic" described them all.
I think a danger would be to not have them to have recorded the entire New Testament for believers, myself.

In present day, what I think you may be thinking of, is what turns into "cult" and that IS dangerous. It is not charismatic there, but it is people following the leader, rather than reading the Bible and being accountable to God more than to man.

With leaders who have charisma enough, this happens.
Jim Jones and the Branch Davidian to name two among many..... many, sadly.

Is it really the leader or the people who cause such "danger"?
So according to your Question the answer is VERY if not "charismatic" but leading people astray. This is what cults do. Lead towards something more than God desires or away from him with things that deceive.
BUT the Bible is full of help: Do not be deceived, etc....
Just stay in the Book, and in prayer and NO Leader can be dangerous for you.

2 Timothy 2:15
Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
Philippians 2:11-13
11 And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
12 Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.
13 For it is God which worketh in you both to will and to do of his good pleasure.

Both Timothy and Philippians above courtesy of the "charismatic" Paul. (If it is in the New Testament, in fact, consider it from those "charismatic" leaders..... leaders enough to write the words we study within the Word of God.)

Acts Chapter 17, Verse 11
These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.

Answer 3

Firstly, you describe the core of a cult... secondly, the danger is the congregation becomes attached to the minister, preacher or whatever title they have more than they do Jesus, The Holy Spirit, or God. The rest follows...

Answer 4

Jim Jones & David Koresh are really good examples of what the dangers are.

Answer 5

check out Islam, or the branch davidian, or jonestown, or a multitude of other cults

Answer 6

You have to move to the jungle and drink kool aid. I don't like kool aid.
