Does destroy always have a bad meaning; which is good, to destroy evil or to destroy good?
Evil does not want to be contained, it tries to spread and corrupt. If presense of evil thrives, then the presence of good will diminish. Destroying Evil works is good.
Good seeks to destroy Evil in word, but good will defend righteousness in various manners.

2 Thessalonians 2:3-10, 12 KJV
[3] Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; [4] who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. [5] Remember ye not, that, when I was yet with you, I told you these things? [6] And now ye know what withholdeth that he might be revealed in his time. [7] For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. [8] And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: [9] even him, whose coming is after the working of Satan with all power and signs and lying wonders, [10] and with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
[12] that they all might be damned who believed not the truth, but had pleasure in unrighteousness.
1 Corinthians 3:16-17 CSB

[4] They that forsake the law praise the wicked: But such as keep the law contend with them. [5] Evil men understand not judgment: But they that seek the LORD understand all things.

[7] Whoso keepeth the law is a wise son: But he that is a companion of riotous men shameth his father.
Ephesians 5:11-14 KJV
[11] And have no fellowship with the unfruitful works of darkness, but rather reprove them. [12] For it is a shame even to speak of those things which are done of them in secret. [13] But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light. [14] Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light.
