C.H. Spurgeon was talking about strife in the church here, but we can easily apply the principle to any organization or group of people.

“…The fire of strife is a terrible evil when it breaks out in a Christian church. … Those who feed the fire deserve just censure, but he who first kindles it is most to blame. Discord usually takes first hold upon the thorns; it is nurtured among the hypocrites and base professors in the church, and away it goes among the righteous, blown by the winds of hell, and no one knows where it may end. O thou Lord and giver of peace, make us peacemakers, and never let us aid and abet the men of strife, or even unintentionally cause the least division among your people.” –CHSpurgeon, Morning and Evening
